King George III (1762-1764) Allan Ramsay (1713-1784)

The picture has something of this: people, portrait, woman, veil, wear, crown, queen, decoration, costume, retro, man, vintage, fashion, lid, jewelry.
Perhaps it’s a close up of a painting of a man in a white and gold outfit with a red curtain in the background and a red and white flag in the foreground.
