Packed with seven different kinds of exciting, mind-bending photo puzzles, this activity book for readers 9 to 12 contains Highlights magazine's Hidden Pictures puzzles, along with spot-the-difference, matching puzzles, mazes, and more, all created from color photographs of such items as butterflies, toys, shoes, a Venetian canal, and rubber duckies. Some are trickier than they look, but all of the answers are in the back of the book.
