6 x 7 1/2 in. silver gelatin photograph of Edison in his later years (ca late 1920s, probably post 1925). Affixed to mat with printed name, signed in margin below. Framed to 12 x 14 in. Edison had some 1,093 patents in his name, not the most of anyone, contrary to popular belief (some have 4 -5000 patents - mostly related to computing), but still a prolific inventor.
