A strange book that I first owned as a child and then subsequently tracked down through a second hand bookshop. It consists of 26 alphabetical colour plates containing, in some cases, many hundreds of items (animal, vegetable and mineral) that start with that letter. The idea (and a competition on the book's release) is to identify as many items as possible and mark them off in the accompanying workbook. So for Z you would have to find a zebra, a zeppelin, a Zulu, the braille representation of Z etc. Fantastic for those with an interest in words, plenty of time on their hands and a slightly odd idea of how to have fun!
