King of Great Britain and Ireland from 1760 until his death in 1820. His reign was marked most notably by the loss of British control over the American colonies. Advancing mental illness rendered George unable to fulfill his official duties during the last decade of his life, during which time the Prince Regent, William IV, ruled in his stead. Ink signature, “George R,” on an off-white 3.5 x 1.5 slip, affixed to a 5.5 x 5.25 light blue slip, along with an affixed embossed seal. In very good condition, with scattered toning and soiling, show-through from adhesive on reverse, some light curling, and a couple letters of beginning of document to lower right. RRAuction COA.
