SOUVENIR Adolphe William Bouguereau (1825-1905)

The picture has something of this: people, portrait, sea, outdoors, woman, water, beach, nature, girl, facial expression, seashore, summer, leisure, happiness, ocean, relaxation, vacation.
Perhaps it’s a painting of a woman in a shawl leaning on a rock with a plant in the foreground and a body of water in the background.
