The majority of prints bearing a photographer's stamp are by Gideon Lewin. The oldest images, a series of contact sheets, probably date to the early 1950s, while the most recent images are from the 1990s. With few exceptions, all are black and white. The seven prints in OSx-1, Folder 1 are mounted on stiff board, presumably for the purposes of temporary display, or are of poor quality and likely work prints.
