Портрет ИН Коцарева 1757—1759 часть 2 - Russian and soviet artists Русские и советские художники

The picture has something of this: people, portrait, royalty, wear, monarch, sash, leader, engraving, jewelry, necklace, veil, woman, man, crown.
Perhaps it’s a close up of a painting of a man in a black coat with gold trimmings and a white shirt with a gold trim around his neck.
