I always love looking at this book! So clever~ It's really fun to read, for kids and adults alike. Walter Wick is awesome, he's one of the guys behind I Spy <3

This is an astonishing book of clever 3d optical tricks by the photographer of the I Spy books. Each page will have you guessing how did he do that! And there are puzzles to be discovered, tricks to be solved, and visual surprises! At the end of the book, are some explanationss, but don''t peek! Half the fun is waiting to see what appears before your eyes!
