Prosper Lafaye; formerly attributed to Eugène Louis Lami – Posthumous Portrait of Princess Marie d’Orléans, Duchess of Württemberg, in her Atelier, Palais des Tuileries Château de Versailles

The picture has something of this: indoors, home, room, architecture, people, seat, castle, temple, museum, monastery, church, furniture, house, inside.
Perhaps it’s a painting of a woman standing in front of a mirror in a room with red walls and gold trimmings and a chandelier hanging from the ceiling.
