Patriot leader (1729-1824) in Philadelphia during the American Revolution and the secretary of the Continental Congress (1774–1789) throughout its existence. Although a lesser-known revolutionary—Thomson was the only person to sign the Dunlap Broadside of the Declaration along side John Hancock. Bank check, 7.5 x 3, completely filled out and signed by Thomson, payable to Abner Barret for $20.00, January 12, 1822. In very good fragile condition, with several vertical folds, paperclip impression to top edge, two cancellation cuts to body, and a partial central vertical separation. A boldy penned example from the then 92-year-old Thomson. RRAuction COA.
