Vest Pocket Kodak Model B (1925-1934)
Yet one more of my personal vintage camera collection…
These tiny folding bed cameras had a unique feature – the “Autographic Back,” perhaps the first primitive version of a data-back! There was a slot in the back of the camera, that could be opened by the photographer, to allow them to write the date of exposure on the back of the film.
This from CameraWiki:-
“`Autographic film and cameras, Eastman Kodak products from 1914 onward, allowed the photographer to enter his or her own notes onto the negative, rather like an early data back. Comments are written with a stylus in a window in the camera back, onto the paper backing of the film, which incorporates a carbon-paper. This leaves the backing slightly translucent where the stylus passed. The writing window is then exposed to the daylight and the inscription burned onto the negative.”.
