Description
Three color 9 1/4″ x 13″ ad with a drawing of race boat owner Stanley S. Sayres and his boat Slo-mo-shun IV. The ad headline says the “Owner of World’s Fastest Boats tells why he uses Champion Spark Plugs”. This ad is larger than my scanner bed so the outer edges of the ad will not be visible in the scanned view.
