Poyarkov, Vladimir Aleksandrovich – Portrait of a palace grenadiers M. Kulakov Hermitage ~ part 10

The picture has something of this: portrait, people, man, lid, soldier, costume, wear, military, vintage, veil, uniform, antique, sword, retro, weapon.
Perhaps it’s a painting of a man with a beard wearing a military uniform and holding a rifle in one hand and wearing a hat with a feather on the other hand.
