These items contain photographs, handwritten notes, clipped and printed images, mounted on gray cardboard. These large cards were used in the preparation and installation of the Halls of Mammals at AMNH. They were originally organized to reflect particular mammals and diorama backgrounds at the museum. Some of the cardboard files and photographs have handwritten notes inscribed by museum artists. Both the cardboard files and their images are slowly disintegrating. The photographs are separating from the boards on which they were originally mounted, and are also fading.
