Books for which you have to collect the pictures ( in the form of stickers ) yourself have been and still are quite populair. The stickers are obtaineble when you buy products of a surtain brand or are given at super-markets if you buy for a surtain amount of money for free. Any way, children love these sticker-books which can have all kind of subjects ( sport, cars, fairy-tails and .... animals ) and I have myself several nice albums of aquarium-fishes, European birds, aviary birds and so on. Because you have to place the stickers yourself at the right place in the book they are normanly quite eductationable and therefor I like the project which has been devoleped in Colombia to produce a sticker-book for the birds of Colombia, the need however still some support : https://www.facebook.com/video.php?v=1305196069546032 ( which sticker book do you have ? )
