Touko ‘Tom Of Finland’ LAAKSONEN
1920–1991, Finland

Touko Laaksonen, best known by his pseudonym Tom of Finland (8 May 1920 – 7 November 1991) was a Finnish artist notable for his stylized androerotic and fetish art and his influence on late twentieth century gay culture. He has been called the "most influential creator of gay pornographic images" by cultural historian Joseph W. Slade.
Over the course of four decades he produced some 3500 illustrations, mostly featuring men with exaggerated primary and secondary sex traits with tight or partially removed clothing.
