No 3A folding pocket Kodak camera, 1907.

Kodak introduced their first folding pocket camera in 1897. This was the first of what was to become a very popular range of folding roll film cameras. The No 3A FPK, produced between 1903 and 1915, was one of the most popular models. It took postcard-sized photographs. Focusing is achieved by extending or collapsing the bellows to increase or decrease the distance between the lens and the film.
