Harold A. Parker Studio Collection of Lantern Slides and Transparencies

The Harold A. Parker Studio Collection of Lantern Slides and Transparencies consists of 96 hand-colored lantern slides and autochrome lantern slides and 52 2 x 2 in. color transparencies (copies of earlier hand-colored photographs), ca. 1900-1930, depicting, for the most part, unidentified houses, landscapes, plants and gardens in and around Pasadena; the Huntington Hotel in Pasadena; aerial views, presumably of Pasadena; mountain lakes and landscapes; desert landscapes and flora; the Grand Canyon, Pueblo ruins, and the Petrified Forest; unidentified landscapes; and the aftermath of the 1906 San Francisco earthquake. Many of the unidentified landscape images may depict Lake Tahoe and its environs.

The collection does not contain any of Parker's Tournament of Roses photographs.

It is not known whether Harold Parker traveled to San Francisco after the earthquake, and thus the attribution of the transparencies is questionable.
