Dawe George – Portrait of Nikolai Nikolaevich Rajewski Hermitage ~ part 04

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