Over the years we've found quite a few of these caps from Turtle Wax automotive wax/polish. In 1941, Ben Hirsch, the founder, traveled around Chicago to sell his product first called Plastone. He would station himself in a parking lot, polish one fender of a car and wait for the owner's return. Then Ben would sell them a bottle to finish the job. While in Turtle Creek, Wisconsin he was struck with the idea of "The Hard Shell Finish." The name of the town along with the by-line clicked. Turtle Wax is now the largest automotive appearance product company in the world. The top hat on the logo came from Hirsch's hobby as an amateur magician.
"Turtle Wax gives a magic shine."
