Portrait of Baron Antoine Jean Gros (1771-1835) Aged 20 Francois Pascal Simon Gerard (1770-1837)

The picture has something of this: people, portrait, lid, wear, bonnet, veil, woman, cape, Renaissance, retro, wig, dress, engraving.
Perhaps it’s a painting of a man with long hair wearing a black hat and a green jacket with a red sash around his neck and a black top hat on his head.
