Description
Black and white 7 3/4″ x 10 3/4″ ad that attempts to explain “Why Firestone tires hold all records”. It talks about the quality of the cords used on their tires by beginning with the claim that “Firestone owns and operates the world’s largest exclusive cord fabric mills”. It then talks about the process which first includes twisting the cords before gum dipping them which “saturates and insulates every fiber of the cord with pure rubber”. These methods are what allows them to make the claim that “these tires hold all world records for speed, safety and endurance” and allows you to get “More Miles Per Dollar”.
