The Roland G. Holmes Collection of Oregon and Washington Postcards consists of photographic and picture postcards as well as photographic prints of Oregon and Washington scenes. About a third of the images depict scenes of the Columbia River Gorge and Columbia River Highway, including waterfalls, Vista House, highway viewpoints, and Beacon Rock. Images of many other notable Oregon and Washington landmarks are part of the collection, including Mount Hood, Mount Rainier, and Three Sisters; Silver Creek Falls; Crater Lake; the Pacific Coast in Oregon and Washington; and the cities of Portland, Oregon, and Seattle, Washington.
Most of the images of the Columbia River Gorge and Highway were taken by Ralph I. Gifford; an image by Cross and Dimmitt is also included. The collection includes high-resolution digital images scanned from the postcards and photographic prints by Zoe Ann Holmes as well as an item-level list of the images with detailed descriptions.
An addition to the Roland G. Holmes Collection (Accession 2012:068) consists of 70 postcards collected by Holmes that depict a variety of natural landscapes and urban views throughout several states including California, Utah, Colorado, Oregon, Nevada, and Kansas. The two views of Oregon document Willamette Falls and Crater Lake. Nine of the postcards contain messages addressed to Elma Stump Holmes, Roland's mother. In addition to the original images, this accession also includes a cd containing digital files of the postcards scanned as TIF files and a printed index to these files with the images and file names displayed.
