Портрет АС Пушкина 1836 Petr Sokolov (1791-1848)

The picture has something of this: portrait, man, people, antique, vintage, engraving, person, retro, wear, soldier, jacket, military, army, lithograph.
Perhaps it’s a drawing of a man in a suit and bow tie sitting in a chair with his arms crossed, looking to the side, with a serious look on his face.
