A truly handsome, sepia-toned Photograph Signed, “Thos A. Edison”, with his bold umbrella paraph, under his image, on the photographic surface. Edison is depicted in a 1/2 length, full face bust pose. The image is by Walter Scott Shinn, with his photographer’s imprint and copyright mark in the image. The smallest of edge wear, else extremely fine condition. The overall size measures 7 x 10 inches. An attractive ‘simply’ signed image of the great inventor, that would display magnificently!
