The present portraits are versions of Ramsay's celebrated portrait types of King George III and Queen Charlotte, of which the prime originals are respectively in the Royal Collection (see O. Millar, Later Georgian Pictures in the Collection of Her Majesty the Queen, London, 1969, I, p. 95, no. 996); and in the Schloss Wilhelmshhe, Kassel. Many versions of these portraits were painted to satisfy the demand from the King's and Queen's friends and relations, official institutions, fellow sovereigns and the King's representatives overseas. When visiting Ramsay's studio in Soho Square Joseph Moser remarked that he found 'his show-room crowded with portraits of His Majesty in every stage of their operation. The ardour with which these beloved objects were sought for by distant corporations and transmarine colonies was astonishing; the painter with all the assistance he could procure could by no means satisfy the diurnal demands that were made in Soho Square upon his talents and industry'.
