Argunov Nikolai Ivanovich – Portrait of Count Nikolai Petrovich Sheremetev Hermitage ~ Part 01

The picture has something of this: portrait, people, wear, man, leader, jacket, retro, famous, vintage, cape, royalty, sash, profile, mustache, face.
Perhaps it’s a painting of a man with white hair wearing a green and gold uniform and a star in his left hand and a cross.
