National Geographic : 1920 Dec
WHEN you buy Listerine Tooth Paste you'll find an unusually interesting circu lar in the box. It's put there for your benefit, and we advise you to read it. This circular tells you carefully and simply-in a way that you can believe-why Listerine Tooth Paste is the right dentifrice to use. Especially, it tells you why an acid paste is best. Listerine Tooth Paste is made by the makers of Listerine, to clean your teeth perfectly and help you to take care of them. Buy a tube and read the circular first before starting to use the paste.
