A picture of the slogan posted in the Texas Carlsbad Well pavilion with "proof" that a Cadillac, with its radiator filled with mineral water, was rejuvenated with enough "pep" to pass a Chevrolet. Please note: The first Cadillac V-8 engine was introduced in 1914 as the 'Type 51' engine, so this photograph may be dated to 1914 or thereafter. The "Over" section is not illustrated. It probably contained more braggadocio---or, perhaps, what happened next to the two cars.
