Collection consists of approximately 600 negatives used to produce photographic postcards. The photographs date from 1930 to 1970 and depict landscapes, landmarks, city streets, storefronts, and tourist destinations across Oregon. A selection of places and events represented in this collection include Breitenbush Hot Springs, the Columbia River Gorge, Crater Lake National Park, Oregon Caves National Monument, The Pendleton Round-Up, Petersen Rock Garden, and Singing Springs Ranch. Also included are street scenes from cities and towns in all regions of the state.

Many of the negatives have original postcard series numbering and a photographer's signature written directly onto the film. Three photographers are represented in the collection; their signatures identify them only as Christian, Perkins, and Ellis. About 70 percent of the work in the collection is attributed to Christian. It is unknown whether the photographers were employed by the Gilliam Portrait Studio and Camera Shop. The studio was likely a purchaser or publisher of their negatives.
