Josselin de Jong, Pieter de – Mevr. A J Zubli-Maschhaupt, 1887 Rijksmuseum: part 3

The picture has something of this: people, portrait, man, wear, woman, leader, elderly, royalty, administration, lid, music, theater, two, jacket, outfit.
Perhaps it’s a painting of a woman in a black dress sitting in a chair with her hands on her knees and her right hand resting on her left knee.
