Amsterdam: Tierie (1904). 178pp.
Hirschfeld was an important theorist of sexuality and a prominent advocate of gay rights in the early 20th century. This early study of homosexuality was an early articulation of his beliefs about the nature of homosexuality, citing numerous historical examples. Illustrated with several folding plates. The text was translated in to Dutch by "W" and appears to be a version of a text published the previous year by Max Spohr.
Very good in contemporary boards, light wear to covers and edges.
