Jan van Haasteren studio
The Jan van Haasteren studio includes a total of 5 artists:
| Name Artist | At Jan van Haasteren Studio? |
|---|---|
| Dick Heins | Ja |
| Robert Derks | Ja |
| Mars Gremmen | Ja |
| Jan van Haasteren | Ja |
| Wilma van den Bosch | Ja |
| Marco Eisinga | 2017 - 2021 and from January 2026 - present |
Marco Eisinga has also drawn puzzles under the name 'Jan van Haasteren', but he no longer belongs to the Jan van Haasteren Studio. This studio was founded in 2013 to meet the high demand for Jan van Haasteren puzzles. Nuance about the founding date: Jan van Haasteren studio was founded at the end of 2013 and the first puzzle that appeared under the name Jan van Haasteren Studio was Winterfair. However: only in August 2014 was the launch of the Jan van Haasteren studio for the general public. The first puzzle that appeared under the name with Jan van Haasteren Studio was the puzzle 'winter fair' - signed by Robert Derks. So other artists work under the name 'Jan van Haasteren' in this studio. In this way, the work and production of Jan van Haasteren can also be continued, should Jan van Haasteren (born 24 February 1936) pass away.

Artists who have left the Jan van Haasteren Studio – AND returned!
1. Marco Eisinga
Marco Eisinga joined the Jan van Haasteren studio in 2017 and his first puzzle for the Jan van Haasteren Studio was 'Koningsdag'. That's this puzzle:

Sometime in 2021, Marco Eisinga left the Studio. In a Facebook post Marco himself made, he stated, "After my divorce, I fell into a depression due to financial stress. I've been picking things up again for a while now. I just don't know if I'll ever be able to illustrate for the Jan van Haasteren Studio again because I have ADD, and being self-employed with ADD is a no-go." However, the following message appears in a post on the website janvanhaasteren.nl on February 16, 2026:
As of January 2026, Marco Eisinga has officially joined the Jan van Haasteren Studio. With his arrival, the studio has grown to no fewer than six artists, a wonderful milestone that we are incredibly proud of. In January 2026, Marco Eisinga will be part of the Jan van Haasteren Studio again!

The first puzzle published under the name of 'Jan van Haasteren Studio'
The first puzzle that appeared under the name with Jan van Haasteren Studio was the puzzle 'winter fair' - signed by Robert Derks. That's this puzzle:

How do the members of the Jan van Haasteren Studio work together?
I have been able to find nice input from Rob Derks himself on Facebook through this post.
– Question from someone:
“Perhaps you can answer my question Rob. Who comes up with the topics for the puzzles? Is that commissioned by Jumbo and then you get to work and several artists work on 1 puzzle and if so, who decides who draws which part? You sign for Jan van Haasteren, but also for yourself. Isn't it difficult to keep adapting your drawing style, one time your own style and then again JvH style and not copying the JvJH jokes into your own puzzles? Do you also have things that keep coming back in your own puzzles?”
– Answer Rob Derks:
“We meet with the studio staff a few times a year to discuss the drawn puzzles and to go through the planning and the new topics. Everyone contributes ideas and we always look at the list of ideas from puzzlers. Jan, Dick and I will then each work on their puzzles. Drawing in different styles is sometimes a bit of switching, but on the other hand, Jan's drawing style has also been a source of inspiration for my own style for years. Otherwise, of course, I wouldn't have been asked to come and draw for the studio.”
– Question from someone:
“So the three of you don't work together on 1 puzzle? And is there really a studio where you draw together or is that just the name?”
– Answer Rob Derks:
“That's right, we each work on our own puzzle. And we all draw at our own workplaces. But luckily we have telephone and internet, so we e-mail Jan our sketches in between and then discuss them. The only puzzle that Jan, Dick and I have worked on is the Chocolate factory (Jan sketch, I work out and ink and Dick color)”
Explanation, the Chocolate Factory puzzle is this one, so the only puzzle that both Jan van Haasteren AND Dick Heins AND Rob Derks have worked on together (published in 2013):

Jan van Haasteren Studio 10 years in 2023 – Exhibition in Harderwijk
In 2023, the Jan van Haasteren Studio will be 10 years old – so Jumbo takes the year of foundation 2013 (not 2014) as a starting point. How is this anniversary celebrated? There will be a JvH Studio exhibition City museum Harderwijk. This exhibition is called: “All kidding in a piece!”. The exhibition can be seen from May 2023 to early January 2024.
Why is this exhibition actually in Harderwijk? The reason is the friendship between Jan van Haasteren and Marius van Dokkum. Who is Marius van Dokkum?
“Marius van Dokkum is a Dutch artist, born in 1957. He is known for his realistic paintings and drawings with a humorous twist. His work often depicts everyday scenes and characters, depicting human nature and the absurdities of everyday life in a humorous way. Van Dokkum started his career as an advertising artist before fully concentrating on his own art. His paintings and drawings are characterized by detailed craftsmanship and a lively color palette. He often uses warm, inviting colors to create a cozy and nostalgic atmosphere. Marius van Dokkum's work is loved by both art lovers and the general public because of the recognisability and humor it radiates. His paintings and drawings have been exhibited in various galleries and museums in the Netherlands and abroad. He has also published several books collecting his artwork. All in all, Marius van Dokkum is a talented Dutch artist who is known for his realistic paintings and drawings with a humorous approach.”
Because: in 2022, Jan van Haasteren will pose for Marius van Dokkum to have a beautiful self-portrait made. A friendship develops between the two artists. Marius van Dokkum then invites Jan van Haasteren to celebrate the 10th anniversary of his studio in the museum in Harderwijk. Because Marius also has something to celebrate in 2023: then the Marius van Dokkum Museum in Harderwijk will be 5 years old!

Update: as of January 26, 2021 artists on the side of the puzzles
As of January 26, 2021, there has been an update in the house style of the Jan van Haasteren puzzles. From now on, the designers of the puzzle will be placed on the sides of the puzzles. What does that look like? For example:

Update: as of January 26, 2021, the fixed recurring elements are on the back of every box
since the whole box has changed in look-and-feel, now also for the first time the fixed recurring elements are explained on the back of each box. That was unknown to many people. It's really nice that names and explanations are included. I've made a whole list of fixed recurring elements in each puzzle. On this page you can see what Jan van Haasteren hides in every puzzle.
Image 1 on the back of the box – the persons or characters or figures that appear in almost every puzzle. Above it reads 'Members of the Jan van Haasteren Family':

Image 2 on the back of the box – the 3 artists of the Jan van Haasteren Studio, you have a little idea of what they look like. And did you know that these artists also regularly draw themselves in their puzzles, or each other? Also take a look at this page 'fixed recurring elements':

Update: as of April 9, 2022, all Jan van Haasteren puzzles have become sustainable
– How do you recognize that this puzzle is sustainable?
You can recognize that this puzzle is more sustainable because at the bottom left of the box there is a green square that it is made of sustainable material, on this logo it says '100% Recycled Cardboard'. That's this logo:

– What is more sustainable about this puzzle?
Until now, the puzzle that comes in the box has always been packed in a plastic bag. As of April 9, 2022, Jumbo will switch to puzzles in paper bags in the box with the Jan van Haasteren puzzles. Nice action!
All sustainable features summarized:
– All puzzles will be made from 9% recycled cardboard from April 2022, 100
– The plastic shrink film that normally fits tightly around the puzzle has been replaced by two stickers; with these two stickers the lid is attached to the box of the puzzle
– The plastic bag containing the puzzle pieces has been replaced by a paper bag
I made a video of the new box. I got the brand new box when I got the puzzle'Fair of the future' ordered:
NB: the two stickers around the puzzle do cause a problem: if you want to remove these two stickers from the puzzle box, you almost always damage the box, you tear off a piece of the box. And that is very annoying. Solution? Options: Take a potato peeler and cut the two plastics in half and leave them attached to the box. They are transparent, so you can't see it.
Update: as of February 4, 2023, the numbering of the JvH puzzles will change
As of February 4, 2023, the numbering of all puzzles will be permanently changed. That was set in motion with the puzzle'From Below' – signed by Jan van Haasteren. This one has a number 1110100025, this puzzle:

That is really a very different numbering from what was always done until then. I inquired with Jumbo and got this as an answer:
“We started with ten-digit article numbers to be able to comply with unique coding for all our articles in the future.”
Special, because the puzzle ''Dia de los Muertos' (Day of the Dead Mexico)' appeared in 2023 only on March 25, 2023. However, the explanation for this is that this puzzle was already planned to be released in November 2022. And that is why this last puzzle still has the old numbering with number 20077.
For example, you see the image below, from now on every number starts with '111010' and then a number comes after that. The number of the puzzle is now always above the barcode. You then have this number for example: 1110100325. See:

Puzzles published by another party – starting with '11198…..'
In the old numbering, the Jumbo puzzles that were published by another party (Kruidvat, Intertoys, Aldi, Albert Heijn, started. the Scandinavian puzzles etc.) always with an '8'. In the new numbering, Jumbo puzzles published by a party other than will henceforth start with '11198…..', for example the puzzle 'Albert Heijn at the Zaanse Schans', this one has the number 1119801963.
Update: As of January 1, 2025 new numbers for all old boxes AND new dimensions of the puzzle boxes
Jumbo is introducing new, more sustainable square puzzle boxes from 1 January 2025. The boxes have a new layout and compact packaging. Due to the smaller dimensions, the puzzle boxes take up less space. A poster is included with the 500 and 1000 piece puzzles and the combination boxes. The puzzles themselves retain the same size and quality, the puzzle boxes have a new article number. The products are made of 100% recycled cardboard, sustainably produced paper and FSC-certified. The puzzle pieces come in a paper bag and the boxes are sealed with paper sealing stickers. With this new packaging, Jumbo combines style, ease of use and environmental awareness. The dimensions of the new puzzle boxes are:
500 pieces: 25 x 20 x 5 cm
1000 pieces: 25 x 25 x 6 cm
1500/2000/Combi box: 25 x 34,5 x 6 cm
Overview of new issues of the puzzle boxes
When a puzzle in the current packaging is sold out, it will be replaced by the new packaging. As of April 1, all puzzle boxes will be replaced by a new compact format, with the exception of products that are discontinued and therefore not released in the new packaging. To avoid confusion, all puzzles with the new puzzle box format will receive a new article number. Read more about this in 'New sizes of puzzle boxes Jumbo' as of 1-1-2025
The first 1000 piece puzzle to appear in the new box including the poster is in the puzzle created by Mars Gremmen 'NK Don't Get Annoyed' – you can see all about this in the video below:
What does the number on the side of a puzzle box mean?
There is often confusion in the various forums on the internet, about what the number on the side of the puzzle box is. We are talking about this number:

Sometimes this number is sometimes confused by people with the puzzle number. They then think that this number is the number of the puzzle. That is certainly not the case; all puzzle numbers of the Jan van Haasteren puzzles can be found on this page. What it also isn't is the month the puzzle came out. Because sometimes a box says 2021/16, for example. that is not possible because there is no 16th month.
But what is the number? It is the 'umpteenth puzzle' that was released that year. From the image above where it says '2022/12', that means it's the 12th puzzle released in 2022. In 2023, this count will start again with 2023/1.
What feature is on the puzzles: Studio JVH and JOH?
As you can see, on the puzzles or on the boxes of the puzzles there is some kind of abbreviation, namely: 'Studio JVH' or 'JOH'.
For example, the abbreviation 'Studio JVH' (example Cabinet of Curiosities en Rembrandt's Atelier – number 20032):

For example, the abbreviation 'JOH' (puzzle 'Eurovision songfestival):

What do the abbreviations 'Studio JVH' or 'JOH' mean?
– 'Studio JVH' means that the puzzles are drawn by EITHER Dick Heins OR Rob Derks from the Jan van Haasteren Studio.
– 'JOH' means that the puzzle was drawn by Jan van Haasteren himself. Jan van Haasteren is called from birth with the full name 'Johannes'. That is why he signs his puzzles with the abbreviation 'JOH'
