runscottI just thought that the list of back stamps would be larger than ten, and that some photographer stamps and explanations might also have made the book (like 'Conlon', 'Burke', 'Horner', 'Van Oyen', etc.), along with short explanations as to how to identify true ones. Also, a list of less common stamps and known date ranges - like the "Leader Sports" example I sent you - would be helpful (...if you saw a back-stamp in an auction you could look it up in the guide to see if anyone else had seen it before).
Just my thoughts, as a buyer of your books I know you are interested in hearing them.
