autographic film

The No.1 Pocket Kodak is designed to take Kodak’s then-popular but ultimately short-lived autographic film which allows you to use the camera’s metal stylus (which is usually found attached to the brackets just next to the shutter lever but is missing from mine) to record information about the photograph you just took by opening the squat T-shaped window on the rear panel of the camera and writing directly onto the margin of the negative via carbon transfer paper. Regular 120 film also works, of course.
