The Gifford Collection Photographs by Unknown or Other Photographers consists of images created and assembled by the Gifford Family. They include images for whom the photographer is not identified as well as a few images that were taken by other (non-Gifford family) photographers. Many of the photographs described as "unknown photographer" may have been taken by Ralph I. Gifford, his wife Wanda, or his son Ben L. in the course of their photographic work, but their is not enough information provided with the images to specifically and confidently determine the photographer. The images include portrait photographs; scenic views of Oregon landmarks; and photographs of agriculture, primarily in the Willamette Valley, and public buildings and businesses in Salem, Oregon. Of special note are a set of photographs of Berg's Supermarket in Salem, Oregon, and images of canning and food processing operations for green beans, mushrooms, and strawberries.
Images by other photographers primarily depict Oregon scenes such as the Columbia River Gorge and Highway, the Hood River Valley, and the Fossil Beds. Photographers include the Photo-Art Commercial Studios and the Angelus Commercial Studio in Portland.
Most of the images in this collection (about two-thirds) are prints without accompanying camera negatives; the remainder of the collection is camera negatives. These include 4x5, 5x7, and 120 film negatives and several nitrate negatives. Only a few items have both a camera negative and print of the same image.
