PORTRAIT OF LAURENT-DENIS SENNEGON, 1842, OIL ON C(1) Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: people, portrait, wear, man, leader, facial hair, administration, facial expression, music, outerwear, outfit, jacket, seat, furniture, musician, mustache.
Perhaps it’s a painting of a man in a black coat and white shirt sitting in a chair with his hand on his knee and a cigarette in his other hand.
