Portrait of Alfred Beit 1906 Giovanni Boldini (1842-1931)

The picture has something of this: people, portrait, musician, wear, music, man, administration, singer, concert, performance, business, leader, outfit, woman, side view, spotlight, stage, festival.
Perhaps it’s a painting of a man in a black suit and white shirt sitting in a chair with his hands on his lap and looking off to the side.
