Shtemberg, Viktor Karlovich. Portrait cornet Cavalry Regiment, Earl DA Sheremetev Hermitage ~ part 13

The picture has something of this: portrait, people, man, wear, uniform, lid, sword, soldier, military uniform, military, retro, vintage, jacket, weapon, army, coat.
Perhaps it’s a painting of a man in a military uniform with a glove on his left hand and a helmet on his right hand, standing in front of a brown background.
