Litographs puzzles are incredibly fun and challenging. Each puzzle comes together into a beautiful image based on the book. 500-piece puzzles are 15.75" x 21.25" and 1000-piece puzzles are 17.25" x 26.75". With only a few colors in each puzzle, you'll need to use the words themselves as hints to figure out what goes where. Please note that our puzzles are printed using a process called dye-sublimation -- essentially, by pressing the art onto a blank, intact puzzle template. Because of this, the image on the puzzle is very slightly cropped compared to the image on the box, and letters printed right on the edge of the pieces may be a bit blurred.
