For decades, Jan van Haasteren has been creating highly detailed, colorful, and above all, humorous illustrations. Most of his fans immediately look for Jan's trademark – the shark fin, which can be found in every puzzle. However, you can also keep an eye out for other favorite elements – such as Saint Nicholas, false teeth, or Jan's self-portrait, which appear in almost all of his images. Over the years, numerous illustrations by Jan van Haasteren have been released as puzzles with 54 to 5000 pieces by Jumbo.
