Vintage Dinosaur Art: Dinosaurs! A Spot-the-Difference Puzzle Book

There have been a great many 'dinosaur puzzle books' aimed at children over the years, the vast majority of which have been the sort of throwaway fare you'd find in a kiddies' goody bag alongside some cheap 'n' nasty plastic toys, largely devoid of any educational content. Dinosaurs! A Spot-the-Difference Puzzle Book (1995, no relation to anything involving David Norman) is a different matter entirely. Not only is it quite lavishly illustrated, the differences between each pair of pictures are used to highlight interesting aspects of dinosaur science. It's a wonderful conceit, even if the book takes a few strange turns along the way.
