Portrait of Captain A. Kostinitsa. 1,835 Karl Pavlovich Bryullov (1799-1852)

The picture has something of this: people, man, portrait, wear, antique, retro, leader, vintage, elderly, facial expression, lid, two, engraving.
Perhaps it’s a watercolor portrait of a man in a military uniform with a medal on his left hand and his right hand in his other.
