THOMAS A. EDISON(1847 - 1931) American inventor of the electric light, phonograph, typewriter, and microphone, to name a few. Considered perhaps the greatest inventor of the century. Fine sepia S.P. , 7" x 10", a distinguished bust portrait depicting Edison in old age inscribed in the lower margin "To Miss Louise L. Boetsch, Thos A. Edison". With the photographers imprint "Walter Scott Shinn/NY". Very good.
