Pershakov, Aleksandr Fyodorovich – Portrait of Pyotr Semenovich Vannovskiy Hermitage ~ part 09

The picture has something of this: people, man, portrait, lid, wear, costume, mustache, retro, uniform, music, military, facial hair, sword, veil, weapon, vintage.
Perhaps it’s a painting of a man in a military uniform with a long white beard wearing a red, gold, and blue uniform and holding a gold medal in his left hand.
