The Mother and Sister of the Artist, Berthe Morisot
In the National Gallery of Art, DC. There is also a reasonably large version, though less true in color, on Wikipaintings.
The figure of the artist’s mother shows the touch of Morisot’s friend and mentor, Edouard Manet, who repainted passages of the double portrait the day before submission to the Salon, because of Morisot’s worry that the painting would not be accepted.
