Description
Full color 9 1/2″ x 13″ ad for Shell X-100 Premium Motor Oil. The ad has a picture of a group of happy children riding the hardened steeds of a merry-go-round. The ad headline informs us that “5 horsepower drives this merry-go-round. Your car can get 5 to 10 more horsepower with New Shell X-100 Motor Oil Premium“. The text talks about what the Shell Research people have done to allow such a wonderful oil to be produced.
