This book provides hours of challenging entertainment. Hidden in each of the forty-five illustrations is an inconsistency. Either something is missing or something is added. The intruder may hide by virtue of its color, its shape, or it's simply just implausible or out of place within the scene. "Spot the Difference" is challenging but solvable. Clues help out when needed, and (if you give up) the answers are at the back of the book. Anyone that enjoys puzzles will find it diverting, and it's a stand out for kids. The brilliant colors of its jacket and the large format make "Spot the Difference" highly visible in a retail setting. Full colour throughout
