This collection includes original Muybridge glass plate negatives and prints, as well as modern day copy prints of his photographs. Original materials, 1872-1880, include images of the Stanfords' residences in Sacramento and San Francisco, other unidentified estates, and two printed cards from his horse in motion series, 1878. Images represented by copy prints include Canadian Pacific Railway, Indians, San Francisco, Oakland, and several Central America photographs. Also included in the collection is a set of glass slides, primarily of images included in this collection, probably assembled by Harry C. Peterson, former curator of the Stanford Museum.
