Portrait of V.V. Stasov (1824-1906) Ilya Repin (1844-1930)

The picture has something of this: people, portrait, man, mustache, music, musician, elderly, profile, jacket, beard, poet, facial hair, festival, side view, performance, singer, concert, writer.
Perhaps it’s a close up of a painting of a man with a beard and wearing a black suit with a white collared shirt and a chain around his neck.
