Eakins Study of a Girls Head, 1868-69, oil on canvas, Phila Thomas Eakins (1844-1916)

The picture has something of this: portrait, woman, girl, people, profile, nude, vintage, face, light, model, water, fashion, pastel, side view.
Perhaps it’s a close up of a painting of a woman with her back to the camera and her right hand on her chest and her left.
