Portrait of the poet of the Grand Duke Konstantin Konstantinovich Romanov Ilya Repin (1844-1930)

The picture has something of this: people, portrait, wear, music, man, retro, jewelry, musician, necklace, singer, performance, jacket, sword, veil, military, concert.
Perhaps it’s a painting of a man with a beard in a black suit with a red collar and gold trim sitting in a chair with his hand on his chin.
