The profile portraits depict King George III and Queen Charlotte at the time of their marriage and coronation. The King'’s portrait relates to his 1761 'engagement present' miniature and its variant enamelled miniature medallions executed by Jeremiah Meyer (d. 1789), following his appointment as Enamel Painter to the King and Miniature Painter to the Queen. (J. Roberts, George III and Queen Charlotte, 2004, nos. 23, 441 and 444). The Queen wears some of the celebrated diamonds presented to her at the time of her marriage and featured in her 1762 portrait engraved and published by Thomas Frye (d. 1762) and his pupil William Pether (d. 1821) (ibid., no. 21). Their original 'antique' fluted frames, wreathed in pearls and palms, reflect the 1760s Roman fashion promoted by architects such as Robert Adam (d. 1792).
