I Spy School Days: A Book of Picture Riddles

With more than 2.5 million copies sold of the first five books in the series, I Spy has proven itself a winner. The best and brightest yet, I Spy School Days is filled with glorious, color, two-page photographic spreads which feature brainteasers to solve in a blackboard scene, hundreds of tiny objects to ponder in a classification puzzle, Rube Goldberg contraptions to figure out, and more.
