Presumably this is the full-length portrait of George III, painted for him as a present for his son George, Prince of Wales, for which Dupont was paid £63. This was probably the full-length that was stated in The Morning Herald of 23 April 1795 to have been ‘just conveyed by royal orders to Carlton House’. It was originally a straightforward copy of the portrait of George III in Windsor uniform by Thomas Gainsborough (Royal Collection), which Simpson has turned into a Garter portrait. The left background is presumably by Dupont, but the background on the right was apparently completely repainted by Simpson, who added the crown and sceptre to the design. Traces of the original design are still very clear, for example, the original position of the King’s legs and feet can be seen and the lace on the cuffs of the Windsor uniform remains visible. The legs are now clearly based on those in Sir Thomas Lawrence’s portraits of George IV.
