Portrait of Alexandre Dumas Jr 1877 24.5x16.5in Jean-Louis Ernest Meissonier (1815-1891)

The picture has something of this: people, wear, portrait, furniture, man, seat, indoors, room, woman, sit, footwear, two, position, facial hair, pants, side view.
Perhaps it’s a painting of a man in a suit and tie sitting at a desk with a stack of books in front of him and a pile of books behind him.
