Batoni lady mary fox Pompeo Girolamo Batoni (1708-1787)

The picture has something of this: people, woman, wear, portrait, dress, girl, theater, opera, veil, furniture, music, costume, performance, actress, theatre.
Perhaps it’s a painting of a woman in a gray dress with a cat in her lap and a red and white ribbon around her neck, standing in front of a red curtain.
