Description
Full color 10″ x 13 1/2″ ad for their X-100 Motor Oil. The ad has a picture of the creature with two horns who is holding a glass filled with fiery acid which the headline explains that “Your engine makes this much Acid every day…And it’s Acid Action – not friction – that causes 90% of engine wear”. The text claims that this “New Alkaline Shell X-100 Motor Oil counteracts Acid Action” and that it is “Fortified with alkaline ‘X’ safety factors”.
