Novel way to apply lipstick

Every Friday, artist Mitch O'Connell runs a T.G.I.F. post featuring an image from his massive collection of vintage ephemera. This time, it's an old lipstick add, in which a woman is practicing her lipstick applying skills with no hands and closed eyes. The author of the 1974 book, Subliminal Seduction, which I loved reading as a kid, should have included this image in his book. Maybe it wasn't subliminal enough.
