The series consists of slide transparencies from ca. 1930 through 1992, depicting Princeton and environs, including Allenby, Ashnola, Tulameen, Hedley, and Coquihalla. Some depictions of mines, or the areas of mining activities, including Nickel Plate, Coalmont, and Brenda. Featuring predominant coverage of the outdoors, the series includes photographs of many area mountains, creeks, and lakes. Scenes of recreation, including fairs, parades, and rodeos are also available. These slides are mainly attributed to Roy Thomas.
Prints feature photographs of members of the Allison family, with item-level descriptions under development.
