Vogel von Fogelshteyn, Carl Christian. Portrait of Burkhard Richter Hermitage ~ part 12

The picture has something of this: portrait, people, wear, jewelry, woman, vintage, retro, jacket, model, outfit, weapon, lid, outerwear, girl, veil, necklace.
Perhaps it’s a close up of a painting of a man wearing a black uniform with a gold trim around his neck and a hat on top of his head.
