Touko Valio Laaksonen, known by the pseudonym Tom of Finland, was a Finnish artist who made stylized highly masculinized homoerotic art, and influenced late 20th-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 3,500 illustrations, mostly featuring men with exaggerated primary and secondary sex traits, wearing tight or partially removed clothing.
