Portrait of I.S. Kamynin (1808-1874) Vasily Perov (1833-1882)

The picture has something of this: portrait, people, mustache, elderly, man, facial hair, writer, eyeglasses, beard, scientist, lid, poet, jacket, leader, poetry.
Perhaps it’s a painting of a man with a long white beard in a black suit sitting in a green chair with his hands on his chest and a gold medal around his neck.
