Portrait of a military engineer, Captain A. Shevtsova (1847-1919), brother of the artists wife Ilya Repin (1844-1930)

The picture has something of this: people, portrait, uniform, wear, military, military uniform, lid, soldier, leader, army, man, outfit, medal, administration, cap, mustache, captain, war.
Perhaps it’s a painting of a man in uniform with a moustache on his face.
