The Ray D. Gottfried "Photo Story of the Snow Cruiser" Scrapbook was compiled by Gottfried to document the history of the Antarctic Snow Cruiser during construction and demonstration of the vehicle in Chicago in 1939, the transport of the Snow Cruiser from Chicago to Boston, including the crash in Gomer, Ohio, and use of the vehicle in Antarctica. Some content in the scrapbook dates from after the use of the Snow Cruiser in Antarctica, and includes written historical reflections on the vehicle, as well as photographs of historical exhibits and of models or replicas of the Snow Cruiser built at later dates. The scrapbook is composed primarily of scanned photographs, most in color and several taken by Gottfried, as well as newspaper articles reprinted on to copy paper; most are annotated by Gottfried. The content in the scrapbook dates 1939-2004; the scrapbook was assembled by Gottfried in stages, with the first stage completed in 1994, and subsequent materials added at irregular intervals through 2004.
