Portrait of M. V. Dobuzhinsky Konstantin Andreevich Somov (1869-1939)

The picture has something of this: people, portrait, man, wear, leader, facial expression, face, side view, profile, person, facial hair, confidence, pensive, vintage.
Perhaps it’s a close up of a painting of a man wearing a white shirt and a white collared shirt with his hands on his chin and his chin.
