Portrait of Afanasy Fet (1820-1892) Ilya Repin (1844-1930)

The picture has something of this: people, man, portrait, elderly, facial hair, wear, mustache, beard, music, war, military, musician, scientist, leader, soldier.
Perhaps it’s a close up of a painting of a man with a long beard and wearing a black coat and sitting in a chair with his hand on his knee.
