Longhi Pietro (Pietro Falca) (Venice 1702-1783) – The artist in the studio (43x53 cm) 1741-44 J. Paul Getty Museum

The picture has something of this: people, woman, wear, veil, dress, Renaissance, man, two, seat, Mary, furniture, baby, child, portrait.
Perhaps it’s a painting of a woman sitting in a chair next to a man in a green dress and a woman in a pink dress.
