No wonder, the colourful pictures are full of imaginative elements, funny details and last but not least British charm. The really curious thing about it: The artist is colour-blind. With the magical bookcase XXL with 18,000 pieces measuring 2.76 x 1.92 metres, the author and illustrator of children's books was truly faced with his biggest task. He solved them masterfully and created a man-high shelf in which there are countless details to discover. Now it's up to the puzzlers to face the challenge and put 8kg puzzle pieces (in 4 bags) into an impressive overall picture.
