Description
Black and white 10″ x 13″ ad that talks about how the best performance cars use AC Spark Plugs. The ad headline states that “At Daytona AC sparks Winning Performance” and the ad has a chart that gives the results from the 1963 Pure Oil Performance Trials. This ad is larger than my scanner bed so the outer edges of the ad will not be visible in the scanned view.
