Catalogue of Photographic Apparatus, Rochester Optical Co., (Rochester, NY), May 1893, ~6"x9", 56pp

This catalog is 56 pages, whereas the 1891 catalog was only 40 pages.  The Carlton has been added, a deluxe version of the Universal English-type compact camera.  Also added is the Empire State, a less expensive version of the Ideal.  The Folding Premo, a leather-covered hand-and-stand-type camera has been added - as yet only one model, but a model which would prove so popular that by 1897, the Premo would have 17 models and its own 80 page catalog, The Premo Camera.
