Description
Full color 7 1/2″ x 10 1/2″ ad for their Racing Oil. The ad shows a Silver can of this product bold against a background of yellow and the headline claims that “This is no ordinary motor oil”. The text explains this fact by saying “Because no ordinary car needs it” and mentions the mysterious additive, Z-7. This, added to the “finest stock there is – 100% pure Pennsylvania”, makes it worth having in your car, available in grades 20 through 60.
