Portrait of Doctor Constantine Frantsevich Janicki Ilya Repin (1844-1930)

The picture has something of this: portrait, people, music, man, wear, musician, concert, outfit, singer, leader, uniform, light, profile, mustache, veil, facial hair.
Perhaps it’s a painting of a man in uniform with a medal around his neck and a moustache on his left side of his face, looking to the left.
