Madame Stumpf and Her Daughter, 1872, NG Washington Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: people, woman, wear, portrait, dress, girl, tree, veil, two, nude, man, model.
Perhaps it’s a painting of a woman holding the hand of a little girl in a blue dress and holding an umbrella while standing in a wooded area with trees.
