Garde Elizabeth Jane Gardner (Bouguereau) (1837-1922)

The picture has something of this: people, portrait, woman, wear, facial expression, man, girl, music, musician, sit, outerwear, recreation, two, pants, model, fashion, sadness, singer.
Perhaps it’s a painting of a woman in a long dress sitting on a rock next to the ocean with her hand under her chin and her chin resting her chin on her chin.
