Marion and Company was the largest and most important supplier of photographic equipment and materials in Europe by the second half of the nineteenth century. Their expertise as stationers was of great advantage to the expanding photographic market - they supplied card stock for carte-de-visites, cabinet cards, etc., printed with the photographer's name, address and flourishes; they also were publishers of carte-de-visites of famous personage. Auguste Marion, who lead the firm, was also a prolific experimenter and author of photographic manuals. In this short paper presented to the Société Française de Photographie, Marion outlines his variation on the carbon process where "an exposed carbon tissue was put into contact with another sensitized but unexposed carbon tissue and after a few hours the latent image of the first tissue had transferred itself to the unexposed tissue, which could then be developed normally..." (Nadeau, Louis. Encyclopedia of Printing, Photographic, and Photomechanical Processes. 1994).

Neither Roosens and Salu, nor OCLC locate this title; however, Marion did publish a manual of 58 pages on his process in 1873, which is known by a few copies and in digital form, see Roosens and Salu No. 6853.
