Joseph-Désiré Court – Marie-Joseph-Paul-Yves-Roch-Gilbert Mottier, Marquis Lieutenant General (1757-1834) Château de Versailles

The picture has something of this: people, wear, portrait, weapon, military, veil, sword, war, military uniform, soldier, royalty, outfit, uniform, man, lid.
Perhaps it’s a painting of a man with white hair wearing a blue coat and white pants and holding a paper in one hand and a red hat in the other hand.
