Dawe George – Portrait of Nikolai G. Repnin-Volkonsky Hermitage ~ part 04

The picture has something of this: people, wear, portrait, facial expression, man, veil, royalty, outerwear, fame, popularity, retro, leader, vintage, lid.
Perhaps it’s a close up of a painting of a man in a military uniform with a red collar and a cross on his chest, with a green background.
