Diane Arbus’s honest and intimate photographs of people on the margins of society reveal what was extraordinary in the familiar and what was familiar in the extraordinary. Her portraits—straightforward in their technique, highly personal in their choice of subject, and collaborative in their approach— proved to be immediately and profoundly influential on subsequent photography. Already by November 1972, when a posthumous retrospective of Arbus’s work opened at the Museum of Modern Art, Robert Hughes declared in Time that her work “has had such an influence on other photographers that it is hard to remember how original it was.” The portfolio “a box of ten photographs,” conceived and assembled in 1969–71, is Arbus’s first and only distillation of her mature work, containing some of her most iconic images made between 1962 and 1970.
