Rare Photography Advertising Broadside for a Parisian photography studio operated by Allophones Lionel who was active in the 1860s (according to Getty Images). Lionel advertises a guarantee that no photographer had offered: a proof - "epreuve" - of the image before the photograph is printed, and if the client does not like the image, the photographer will take a second photograph and offer a second proof for no additional charge. A caricature of the famed French photographer Nadar appears to sit on a camera in the broadside's highly decorative design. The sheet measures 5 1/2 x 8 1/2 inches and is normally aged with slight chip in upper left corner, else very good condition. Photographs of individuals in the carte-de-vi site style established in the 1850's became more popular in the 1860's with many photographers competing for clients. This richly designed broadside must have appealed to new customers. We have not found another example of this broadside.
