Attributed to Nicolas René Jollain the Elder – Portrait of Louis XIV Holding the Plan for the Maison Royale de Saint-Louis at Saint-Cyr Château de Versailles

The picture has something of this: people, woman, wear, Renaissance, veil, portrait, cape, costume, man, dress, seat, elderly.
Perhaps it’s a painting of a man with long black hair in a blue and white outfit sitting in a chair with a sheet of paper in front of him.
