TLS signed “Thomas A. Edison,” one page, 8.25 x 11, From the Laboratory of Thomas A. Edison letterhead, February 25, 1913. Letter to "R. L. Borden, Premier, Dominion of Canada," in part: "This will introduce Mr. H. C. Record, identified with our organization in Toronto, the R. S. Williams & Sons Company, Ltd. If you can see your way clear I would appreciate your talking to Mr. Record about my Dictating Machine, in connection with any interest in it that you may have. I believe you understand that a considerable number of the members of the Canadian Parliament are at the present time using the instrument." In fine condition. Having invented the phonograph in 1877, Edison introduced the 'Ediphone' dictation machine around 1910. A fabulous letter promoting one of his best-known inventions to a head of state.
