Description
Full color 10″ x 14″ ad that begins with “Leading Airlines Use Champion Spark Plugs For Greater Dependability”. There is a picture of a giant Champion Spark Plug with a tiny aircraft landing at an airport behind it. Farther down it says “Be a Champion Driver – Follow these Rules to Stretch Tire Mileage”. You are urged to switch tires from one wheel to another and to keep your tire pressure up to the correct pressure. It urges you to check your tire pressure once a week.
