The Film Pack was introduced by Kodak in 1903 and was at first called the Premo Film Pack. It was used in the Film Premo camera and was made in quarter-plate, Postcard and 4×5inch sizes. Later it was made in 2¼×3¼ and 5×7inch. The pack contained 12 sheets of film, thinner than single sheet film, each with a numbered paper tab attached; it could be inserted into the holder in daylight. The tabs protruded from the loaded holder; as a sheet was exposed you pulled its tab which moved the exposed film to the back of the pack. The 1920 catalogue of Premo Cameras illustrates a Premo Film Pack Tank for developing 12 films.[1]
As with most Kodak film formats, other makers soon produced equivalents. An Agfa Ansco catalogue of about 1930 lists film-packs in sizes up to 5x7 inch; all have twelve sheets per pack.[2]
