| Unidentified photographer/creator Unmarked but probably a Keystone advertising view of an open cabinet showing four Holmes-Bates Stereoscopes with views stored in the slots above. Excellent condition. This view was probably used as a sales aid for the Keystone salesman. n.d. Stereocard Stereographica - Antique Photographica Courtesy of Bryan and Page Ginns (#13 / 350) LL/11300
