Striking, hand-addressed envelope in careful, impressive script, to “Mrs. Thomas A. Edison, Care Lewis Miller Esq., Akron, Ohio” with the pre-printed return address “New Jersey & Pennsylvania Concentrating Works, Edison Building, Broad St., New York.” The cover is postmarked May 17, 1892, Ogdenburgh, N.J. Accompanied by an uncommon, original full-length photo postcard of Ford, Edison and Firestone. In very good condition, with toning and trivial soiling (largely at edges). R&R COA.
