Portrait of Anton Rubinstein. 1870 H., M., 96x80 Gos. muses. music. cult. them. Glinka, M. Vasily Perov (1833-1882)

The picture has something of this: people, portrait, wear, man, jacket, outerwear, facial hair, seat, furniture, writer, leader, sit, lid, music, engraving.
Perhaps it’s a painting of a man in a black suit and tie sitting in a chair with his hands on his knees and his right hand.
