Anthony van Dyck – Portrait of a Genoese nobleman Liechtenstein Museum (Vienna)

The picture has something of this: people, portrait, wear, woman, man, indoors, music, theater, fashion, jewelry, dress, outerwear, facial expression, opera, performance, jacket.
Perhaps it’s a close up of a painting of a man wearing a black coat and a white collared shirt and holding his hand out in front of him.
