1920 Kelly-Springfield Understated Tire Ad - Have to Look To Notice the Product N1241

This original 6 x 9" magazine ad showcases Kelly-Springfield Tires in a very understated way.  In fact you have to study the ad to catch the inference to the Automobile Tire shown on the Front Driver's side in the picture.  At first glance you might mistake this for a 1920 piece of artwork and not advertising.
