A very nice1 copy of a rare edition of Sanger's monumental historical and global survey of prostitution, practices, the tactics of sex traffickers, the nature of those who "procure" prostitutes, the connection between slavery and the sex-trade, etc., 

At a whopping 700+ pages, this was the most significant work to the time issued on the subject and remains an invaluable resource today. 

Sanger, William W. The History of Prostitution: Its Extent, Causes, and Effects Throughout the World. With Numerous Editorial Notes and an Appendix. New York. Medical Publishing Company. 1897. 709pp.

Large 8vo, near small 4to in original plain blue cloth. Very crisp though with some surface rubbing and a small wax spot on rear board. Interior is exceptionally crisp and clean with light gutter exposure between title and front matter. A very nice example.
