In the early 1910s, San Francisco Police identified prostitutes on RPPC (real photo postcards). The information included names, and actual names, with a description of hair, eyes, height, and weight. Additional cards held more details about residences etc. These came in a large collection I purchased over 20 years ago. They are very rare and I have decided to sell them.
