caption: The image shows a portrait of Maria Antoinette van Oostenryk, a woman with a gentle expression on her face. She is wearing a white dress with a blue sash and a white bonnet, and her hair is pulled back in a bun. Her eyes are looking off to the side, and she has a slight smile on her lips. Her hands are clasped in front of her and her hands are resting on her lap. The background is a light blue color, and the portrait is framed by a thin black border.
