Rembrandt – Portrait of Margaretha de Geer, Wife of Jacob Trip Part 6 National Gallery UK

The picture has something of this: people, portrait, wear, man, facial expression, veil, indoors, woman, elderly, lid, leader, furniture, writer, mustache, knitwear.
Perhaps it’s a close up of a painting of a person wearing a black dress with a white ruffle around the neck and a white collar.
