American forger (1887-1950?) who forged letters from American luminaries. An original Joseph Cosey forgery of a George Washington handwritten letter, 8.5 x 11.5, dated September 15, 1789. The fabrication is signed “Go. Washington.” In fair to good condition with intersecting folds, partial separations along both horizontal and vertical folds, heavy soiling and staining, and small edge tears. While forgeries of equally well-known forger Robert Spring occasionally surface, Cosey forgeries are far scarcer. RRAuction COA.
