Comtesse de la Chatre, Later Marquise de Jaucourt Élisabeth Louise Vigée Le Brun (1755-1842)

The picture has something of this: people, lid, veil, seat, woman, portrait, wear, facial expression, furniture, girl, sit, indoors, bonnet, actress, chair, dress.
Perhaps it’s a painting of a woman in a white dress and hat sitting on a couch with a book in her hand.
