King of Great Britain and Ireland (born 1738) 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 7.75 x 3.25 slip clipped from an official document and bearing an embossed seal. Toning and soiling to top edge slightly touching signature, otherwise fine condition. R&R COA.
