Autographic
The Autographic system for roll film was launched by Kodak in 1914, and allowed the photographer add written information on the film at the time of exposure.The system was patented by Henry J. Gaisman, inventor and safety razor manufacturer. George Eastman purchased the rights for 300,000 US dollars. It consisted of a tissue-like carbon paper sandwiched between the film and the paper backing. Text was entered using a metal stylus, and would appear in the margin of the processed print. The system was never very popular, and was discontinued in 1932.
