American forger (1887-1950?) who forged letters from American luminaries. An original Joseph Cosey forgery of a Benjamin Franklin document, 8.5 x 7.5, dated October 4, 1787. The fabrication is signed “B. Franklin.” In very good condition, with central horizontal and vertical fold, a cancellation cut to center, tape remnants to left corners, paper loss to edges, and scattered light toning. While forgeries of equally well-known forger Robert Spring occasionally surface, Cosey forgeries are far scarcer. RRAuction COA.
