The Vain Parlor Maid (1908)

Original title: Das eitle Stubenmädchen

A housemaid is cleaning a studio. When she sees a sculpture of a nude woman in life-size, lying on a couch, she starts to compare this idealized body with her own. She takes off her clothes one by one, thus revealing her own naked body, and she compares the various parts of her body with those of the statue. The master of the house enters the studio. When he sees his housemaid naked, he tells her to go into the next room, and then goes into that room himself.
