Dawe George – Portrait of Ilya Ivanovich Alekseyev Hermitage ~ part 04

The picture has something of this: people, portrait, wear, man, facial expression, lid, jacket, outfit, leader, royalty, necklace, military uniform, neckwear, outerwear, veil.
Perhaps it’s a close up of a painting of a man in a military uniform with a moustache on his face.
