This book is one of the most talked about banned books for children.Published in 1975, it was fairly recently banned in Seattle for it's photographs of young children engaging in sex play.The book is well known by pedophiles and has been used by them to justify their assulting of children.That being said it is also a valuable resourse for parents of only children to show their children what the other gender looks like without their clothes.The book also contains photographs of adults making love including a lesbian couple.Warning: The book also contains a photograph of a boy and girl urinating.Very hard to find. The Vancouver Public Library used to have two copies, one was destroyed and the other copy is in a special collection.
