Description
Black and white 4 3/4″ x 5″ ad for their uncommon motor oil. The ad has a picture of an active man in a skin diving outfit and a picture of an older man in a business suit driving his car to work. The ad headline asks the question “What do they have in common?” and answers by saying “the uncommon motor oil!”. The ad tries to explain what makes it “uncommon” by saying that it is “100% Pure Pennsylvania, Tri-Ex refined three important extra steps for maximum lubricating efficiency and scientifically fortified to clean as it lubricates”.
