Descriptive Catalogue of Photographic Apparatus and Supplies, G. Gennert (New York, NY), undated c. 1893, ~6"x9", 116pp

This catalog is undated, but the inside back cover refers to Photographic Mosaics 1893.  The testimonial letter on the inside front cover is dated 1890.  This catalog contains a number of brand names, such as Columbian, Magic and Globe, that appear in the Jas H. Smith 1901 catalog and others, despite the fact that those brands are usually associated with items apparently manufactured by the Seneca Camera Mfg. Co.
