Visual Materials
A collection of glass plate and film negatives by amateur photographer and Los Angeles real estate broker George P. Thresher focusing on the American Southwest and Native Americans of the region, particularly of Arizona, and the Gila River crossing area, from ca. 1898 to 1910. The majority of the Thresher Collection contains images of towns and sites in Arizona, including Phoenix, Mission San Xavier del Bac, Montezuma Castle, Peach Springs, and adobe ruins. Photographs of Texas are well represented in the collection, including many views of Missions San Concepcion, San Antonio de Valero (the Alamo), San Francisco de la Espada, and Mission San Jose y San Miguel de Aguayo. There are also images of Colorado (Garden of the Gods, Pike's Peak, and Castle Rock), New Mexico (Santa Fe, Tesuque, and possibly Laguna), and unidentified pueblos. Notable portraits from California are of Victoriano, chief of the Soboba Indians, and his unnamed third wife. There is a separate and very interesting sequence of images depicting the Mount Beauty Mine and its operations in San Diego County, California. A small assortment of lantern slides is at the end of the collection showing Indians of Arizona, California, and New Mexico.
