Danloux, Henri-Pierre – Jean-Baptiste Canthaney, dit Cléry, valet de chambre de Louis XVI (1759-1809) Château de Versailles

The picture has something of this: people, portrait, man, wear, jacket, facial expression, music, tie, musician, menswear, retro, outerwear, indoors, actor, movie, fashion, business, neckwear.
Perhaps it’s a painting of a man with white hair wearing a black coat and a red flower in his left hand and a black jacket over his left shoulder.
