Lorenzo Costa (1460-1535) – Portrait of a young man Part 3

The picture has something of this: people, wear, portrait, lid, cap, man, veil, woman, outfit, facial expression, music, outerwear, theater, winter, adolescent, festival, musician, fashion.
Perhaps it’s a close up of a painting of a man wearing a red hat and a red coat with a black collar and a white stripe around his neck.
