Portrait of George Attwood (1777-1834) * Unknown painters

The picture has something of this: people, portrait, man, wear, lid, neckwear, popularity, cravat, actor, scarf, music, outerwear, facial hair, talent, famous, jacket.
Perhaps it’s a close up of a painting of a man in a black suit and white shirt with a book in his lap and a red curtain behind him.
