Spot the Difference

A large format book filled with high quality photographic doubles, with the necessary slight differences (otherwise it's only half a book!) There's a wide range of quite unexpected and colourful subject matter, with puzzles categorised into levels of difficulty. Some of them are really VERY difficult! To keep up interest, there are some different forms of puzzle including mental jigsaws - all observation based. Answers are provided the back. Paperback, 64 pages, Approximate Size: 28 cm.
