This film format was ultimately replaced by Eastman Kodak's 16mm standard. The unusual film had a frame size nearly as great as the 35mm Academy frame. This piece of film was taken from the home movies of the John D. Rockefeller family of Standard Oil fame. Pretty cool to have your own director of photography on staff. The exact date of this film is unknown.:-)

The system was first introduced in 1912 by Pathé and its goal was to create an amateur format that could not use flammable nitrate base slit from commercial stock.
