Andlau, Armand-Gaston-Félix, Comte Élisabeth Louise Vigée Le Brun (1755-1842)

The picture has something of this: people, furniture, facial expression, man, wear, portrait, seat, room, indoors, sit, outerwear, sitting, confidence, jacket, concentration, pensive.
Perhaps it’s a painting of a man sitting in a chair with a book in his hand.
