Nude Girl Eric Harald Macbeth Robertson (1887-1941)

The picture has something of this: nude, woman, girl, people, portrait, model, ballet, ballerina, sexy, fashion, wear, body, reclining, performance, ballet dancer, beautiful, glamour.
Perhaps it’s a painting of a naked woman laying on a blue blanket with her head resting on the back of the woman’s body, with her eyes closed.
