A Reclining Nude Jules-Joseph Lefebvre (1836-1911)

The picture has something of this: nude, people, woman, sexy, girl, portrait, relaxation, skin, reclining, erotic, fashion, indoors, body, treatment, wear, recreation, health.
Perhaps it’s a painting of a naked woman laying on a red blanket with her head resting on the back of the body of a seated woman with her hands behind her head.
