Portrait SN Marina. 1812. Orest Adamovich Kiprensky (1782-1836)

The picture has something of this: people, portrait, wear, necklace, man, engraving, jewelry, retro, music, royalty, leader, fame, medal, famous, antique.
Perhaps it’s a close up of a painting of a man wearing a uniform with a red ribbon around his neck and a medal on his left side of his neck.
