Nicolaes Maes – An Old Woman Dozing over a Book National Gallery of Art (Washington)

The picture has something of this: people, piano, music, portrait, musician, woman, pianist, room, furniture, sit, seat, wear, indoors, instrument, facial expression, singer.
Perhaps it’s a painting of a woman sitting at a table with a book in front of her and a key hanging from a hook on the wall behind her.
