Elizabeth (1750-1788) Countess of Hopetoun Richard Cosway (1742-1821)

The picture has something of this: people, portrait, baby, face, saint, woman, antique, Renaissance, man, sculpture, god, wig, lid.
Perhaps it’s a portrait of a woman with curly hair wearing a white dress and holding a black purse in her right hand and a blue background with a gold frame.
