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
