Portrait of a Young Englishman Titian (Tiziano Vecellio) (1488/90-1576)

The picture has something of this: people, portrait, necklace, wear, man, jewelry, facial hair, outerwear, veil, lid, jacket, leader, royalty, sweater, music.
Perhaps it’s a painting of a man in a black outfit with a gold chain around his neck and hands in his pockets, holding a knife in his right hand.
