This portrait is a version of the prime original in the Royal Collection for which the Queen sat soon after her arrrival in England (see O. Millar, op. cit, I, p. 95, no. 997, II, pl. 2). This version may well ante date 1763 as Lord Amherst, as Governor of Virginia from 1757-1768, would have been entitled to a portrait of the King from the outset of the reign in 1760 and at least one of the other American Governors was pressing claims in 1761 when the prototype had only just been completed. The frame is probably by René Stone, the King's framemaker, with whom Ramsay had to work (see J. Simon, Frame Studies: II, Burlington Magazine, July 1994).
