It's interactive fun for the whole family! The Life Picture Puzzle books are a publishing phenomenon, New York Times bestsellers, with 1 million copies in print in just ten months. The
concept is simple, entertaining, and utterly addictive: Each page features two full-color photographs that at first glance appear identical. But they contain differences, from the relatively
obvious to the maddeningly subtle, that it's the reader's job to spot. The puzzles are organized into four increasingly difficult categories—Novice, Master, Expert, and Genius. Solutions are
printed on the back of each page.
