Having opened at Gagosian Gallery on Tuesday, the late Dennis Hopper’s The Lost Album is currently being exhibited for the first time in the United States since 1970. The significant body of work shot by the actor, director and photographer during the 1960s captures the establishment-busting spirit of that decade in photographs that travel from Los Angeles to Harlem to Tijuana, and which portray iconic figures including Tina Turner, Andy Warhol, and Martin Luther King, Jr. The Lost Album in its entirety comprises over 400 black and white photographs taken between 1961—when his first wife Brooke Hayward gave him a Nikon camera for his birthday—and 1967. He would not make photographs again until the early 1980s.

Exhibited in its entirety, The Lost Album‘s photographs are uncropped and produced with available light, with Hopper’s preference for full-frame adding to his candid approach. The body of work reveals casual portraits of artistic luminaries, leading actors and musicians as well as stirring images of the Civil Rights Movement. There are also hippie gatherings, the Apollo 11 lunar landing, Mexican bullfights, and catchy advertisements for popular cars, soft drinks, and newspapers.

The Lost Album runs through June 22, 2013.
