Portrait SP Chokolova. 1887 Valentin Serov (1865-1911)

The picture has something of this: people, portrait, facial hair, man, mustache, wear, leader, writer, engraving, jacket, side view, beard, priest, music.
Perhaps it’s a close up of a painting of a man with a beard wearing a black suit with a white shirt and black tie and a white wall in the background.
