Signed Reproduction of the First Fax Sent by Ranger of President Coolidge

Outstanding and historically important signed reproduction of the very first facsimile sent by Ranger -- a 5.5 x 3-inch image of President Calvin Coolidge, printed on heavy stock and captioned "FIRST PHOTORADIOGRAM - NOVEMBER 28, 1924." The image was mailed to a colleague in Uruguay, S.A. in December 1924, just days after the original was sent and is accompanied by a hand-typed note (in Spanish) that was attached to the verso of the facsimile. Translated in part: "I have been looking forward to receiving your letter from Le Janos Montevideo and am pleased to enclose some photographs of the first transmissions to have passed.and have signed it as you requested. There was great interest by the public regarding the radio photography. I was curious about the motive for why people have asked for them.but I have attributed it to a desire for one to own a Test. With my good sincere appreciation for your good wishes for our work.and my best wishes for the New Year." Ranger signed in fountain pen below the "facsimile" image of President Calvin Coolidge. Also included is a second photoradiogram, also sent on November 28, 1924, possibly of British Prime Minister Stanley Baldwin, which would have been transmitted from London to the United States upon receipt of the Coolidge image. It is signed beneath the Prime Ministers image. Very good condition. American electrical engineer and inventor of the first Fax machine and the magnetic tape recorder. He received an Academy Award in 1956. As a designer for the Radio Corporation of America (RCA), Ranger invented the wireless photodiogram and sent a photograph of President Calvin Coolidge from New York to London on November 28, 1924. This became the first photo picture reproduced by trans-oceanic radio facsimile. Commercial use of Ranger's product began two years later. Despite Rangers incredible inventions he is virtually unknown and is quite rare in any form.…
