Portrait of P.P. Zhdanovich Pavel Fedotov (1815-1852)

The picture has something of this: people, man, portrait, wear, pants, weapon, military, administration, furniture, war, seat, leader, outfit, soldier, jacket, lid, indoors.
Perhaps it’s a painting of a man in a military uniform sitting in a chair in a room with a desk and a lamp on the side of the room.
