General Jean Baptiste Kleber Jean-Urbain Guerin (1760-1836)

The picture has something of this: portrait, people, woman, man, wear, outerwear, smoke, fashion, jacket, model, music, elderly, jewelry, dress, veil.
Perhaps it’s a painting of a man with white hair wearing a black coat and white gloves and holding a cane in one hand and a white glove in the other hand.
