Hi - No it doesn't have images of the backs and that is unfortunate. It can be a useful reference but really is just an overview. Though I have been able to find many buttons that have been posted on Tnet within. The first section is a history of different types of buttons and how they are made and that is interesting.
I bought my copy used and I think I shopped around for a while until I found one at a good price. I think about $15 would be my max if I were buying this book but I also really like to help solve things here and will take any help I can find even if it is incomplete
