Marie-Joseph-Yves-Gilbert du Mortier, marquis de La Fayette (1757-1834) – Boilly, Louis-Léopold Château de Versailles

The picture has something of this: cavalry, people, man, wear, woman, mammal, two, seated, motion, lid, recreation, veil, competition, equestrian, military.
Perhaps it’s a painting of a man standing in front of a horse and a man in a red and white uniform holding a horse’s bridle.
