caption: The image shows a painting of a woman in a blue dress and hat, holding a stick in her hand, framed in a photo frame. The woman is believed to be the Duchess of York, as indicated by the title of the painting. She has a regal air about her, with her hair pulled back and a gentle expression on her face. Her dress is a deep blue color with a high neckline and long sleeves, and her hat is a wide-brimmed style with a feather-like texture. She is standing in a graceful pose, her hands clasped in front of her.
