Self-portrait in the mirror Konstantin Andreevich Somov (1869-1939)

The picture has something of this: people, portrait, man, wear, leader, side view, facial hair, facial expression, profile, royalty, lid, light, face, mustache, outerwear.
Perhaps it’s a close up of a painting of a man in a suit and bow tie with a mirror in front of him and another man in the background.
