Anton-Raphael Mengs – Portrait of John Viscount Garlies, later 7th Earl of Galloway, as Master of Garlies Los Angeles County Museum of Art (LACMA)

The picture has something of this: people, portrait, wear, man, opera, woman, performance, music, jacket, outfit, theater, musician, fashion, theatre, model, outerwear, singer.
Perhaps it’s a close up of a painting of a person wearing a brown coat and a white shirt and holding a hand out in front of a black background.
