Mizer produced about a million images, and thousands of films and videos before he died on May 12, 1992. During the late 1960s and early 1970s, the advent of 16 mm film cameras enabled these photographers to produce underground movies of gay sex, male masturbation, or both. Sales of these products were either by mail-order or through more discreet channels. Some of the early gay pornographers would travel around the country selling their photographs and films out of their hotel rooms, with advertising only through word of mouth and magazine ads. The 1960s were also a period where many underground art-film makers integrated suggestive or overtly gay content in their work. Kenneth Anger's Scorpio Rising (1963), Andy Warhol's Blow Job (1963) and My Hustler (1965), or Paul Morrissey's Flesh (1968) are examples of experimental films that are known to have influenced further gay pornographic films with their formal qualities and narratives. Also of note is Joe Dallesandro, who acted in hardcore gay pornographic films in his early 20s, posed nude for Francesco Scavullo, Bruce of L.A. and Bob Mizer, and later acted for Warhol in films such as Flesh. Dallesandro was well-known to the public. In 1969 Time called him one of the most beautiful people of the 1960s, and he appeared on the cover of Rolling Stone magazine in April 1971.
