Portrait SD Mstislavsky. 1929 Kuzma Sergeevich Petrov-Vodkin (1878-1939)

The picture has something of this: people, portrait, man, leader, famous, person, elderly, facial hair, face, sculpture, saint, veil, woman.
Perhaps it’s a close up of a painting of a man with a moustache on his face and in a black shirt with a mountain in the background.
