Just based on the illustration I'd think the copy should read "Your dead ancestors, newly jealous, will melt your face if you use our product!" But the story is actually more prosaic:
Suppose you were out most of the night. No need to tell the world about it. Greet the cold, grey dawn with a smile--with a sparkle in your eye, instead of the "burnt holes in a blanket" effect. Chase the tired, sleep-famished look from your face. The set wooden expression that everybody knows is the "morning after" look.For the provincial boor (that's you and me!) a convenient note reminds us: "Pronounced Foo-Zhaire Royal."
