A photographic picture taken on an iron plate by a collodion process; -- familiarly called tintype.
One of the photographic processes of the 1860s, in which the photographic emulsion was spread on a thin piece of iron. Presidential items were made by placing a small ferrotype in a quarter size brass disc that could be tied to the coat lapel by a ribbon. A ferrotype has a picture we usually call a Tintype. 1860 Ferrotype for John Bell for President
Lapel device consisting of a tintype photograph and a frame. Unlike later lapel pins, ferrotypes were not produced by a printing press but by the photographic method of exposing a light sensitive surface to a negative and then developing the image. The ferrotypes were made from a large sheet of metal onto which a light sensitive surface had been applied. Numerous photographs were made on the sheet, and then the photos were cut out. The photos were then mounted in a brass frame. 1860 Ferrotype for John Bell for President
