Lipgart, Ernst Karlovich – Portrait of a cornet of the Life Guards Hussar Regiment P. Rajewski Hermitage ~ part 07

The picture has something of this: people, sword, wear, uniform, man, military, weapon, outfit, portrait, armor, soldier, military uniform, war, costume, royalty, monarch, warrior, knight.
Perhaps it’s a painting of a man in a uniform with a pipe in his hand and a hat in his other hand.
