Dear Mike, It can be possible that photographed people in the book are prostitutes. Really I don't know. But they are models in fact of photography. A lot of famous artist use for their models people with ,,past". What Goya and his Naked Maya, Manet with his Olympia, Modigliany and what about famous New York photographer Bern Stern? His book Eros brought suit its publisher. There are hundreds of world famous artist from different country, who use prostitutes for models. Yes, because they are cheap. This fact doesn't mean that his arts are worse then other, World`s Galleries prove it. And I have a question to you. How can you know, these information if you didn't participate?
