Lorimier, Henriette – François-Charles-Hugues-Laurent Pouqueville Château de Versailles

The picture has something of this: people, portrait, man, jacket, outerwear, coat, wear, lid, neckwear, facial hair, vintage, retro, mustache, model, fashion.
Perhaps it’s a painting of a man in a white coat sitting in a chair with his hand on his lap and his right.
