Johann Georg Ziesenis – Portrait of Princess Frederika Sophia Wilhelmina (1751-1820) Mauritshuis

The picture has something of this: people, wear, woman, portrait, man, veil, war, furniture, outfit, two, seat, soldier, girl, military, facial expression, music.
Perhaps it’s a painting of a woman in a green dress sitting in a chair with a dog on the other side of the chair.
