Elizabeth Hempstead Elliott Mount (1816-1858, artist’s wife) “Rose Of Sharon” Shepard Alonzo Mount (1804-1868)

The picture has something of this: woman, fashion, dress, portrait, girl, veil, model, people, beautiful, wear, retro, jewelry, glamour, hair, sexy, music, fashionable.
Perhaps it’s a painting of a woman in a yellow dress with a flower in her hand and a red hat on her head.
