Description
Full color 9 1/2″ x 13 1/2″ ad has a drawing of a smiling Carl A. Peterson against a black background. The ad has him describing the long term success he has had by using their oil as he admits to using it for over ten years. One of the necessary selling points of oil for this stage of the development of the automobile engine was that it needed to be referred to as ring-free oil. This ad is larger than my scanner bed so the outer edges of the ad will not be visible in the scanned view.
