Portrait AP Petrova – Vodkin, mother of the artist. 1909 Kuzma Sergeevich Petrov-Vodkin (1878-1939)

The picture has something of this: people, portrait, elderly, man, mustache, face, facial hair, leader, veil, famous, painter, monk, wear.
Perhaps it’s a close up of a painting of a person wearing a blue shirt and looking at the camera with a serious look on his face, with a green background.
