Portrait Medallion of Louis XVI (1754-1793) Joseph Siffred Duplessis (1725-1802)

The picture has something of this: people, man, portrait, Renaissance, god, royalty, book, veil, saint, wear, monarch, crown, woman, church.
Perhaps it’s a portrait of a man in a suit with a star on his chest and a blue sash around his neck, in a gold frame with a white background.
