I found this book at Rust Belt Books in Buffalo. It was originally written in German and translated into English for the UK market in 1985. I really like the layout and the way the pigeons are photographed against alternating color backgrounds. I find the bizarre range of pigeon breeds fascinating and slightly alarming. It is a very thorough and technical book, there are gruesome pictures of pigeon autopsies that illustrate the effects ofdiseases and parasites.
