Portrait of Francesco I d’Medici (1541-1587) seated half-length, wearing a Doublet Alessandro Allori (1535-1607)

The picture has something of this: people, portrait, man, wear, jacket, veil, facial hair, leader, lid, sit, outerwear, music, seat.
Perhaps it’s a close up of a painting of a man wearing a red shirt and holding a black object in one hand and a white object in the other hand.
