The collection includes 52 photographs and a map that were part of the Cambodia Witness Exhibit (1983). It also includes the exhibit brochure, catalog list, and a file on the exhibit from its coordinator, Joan Libby. The photographs were taken by David Hawk during two trips to Cambodia in March 1981 and April 1982. The exhibit includes images of the prison at Tuol Sleng, prisoners (from existing files), survivors, mass graves, and the destruction of temples and churches. The exhibit was curated by Joan Libby for Amnesty International (USA)
