One of several related photographs housed in this negative sleeve that document the process of phototelegraphy -the process of transmitting photographic images over telephone wire. Though there were advancements - namely the Telediagraph, the Belinograph, and the Telephotograver (invented by Los Angeles Times managing editor Ralph Trueblood) – the technology left much room for improvement. In the 1930s, the Associated Press began working with Kodak to perfect the technology. On January 1, 1935, the AP sent the first photograph out over its Wirephoto service to 47 affiliated newspapers across the United States.
