A three quarter length figure of King George III seated in a General Officer's coat with the ribbons and star of the Garter, wearing the Garter around his leg; his hat and sword resting on a nearby table. Finished in 1771 it portrays the king at age 33, with a steady serious gaze, a ruddy healthy face, and a calm assured demeanor.
