Steve, I wonder what the dates on the Platinum plates would be (1960s?). Which leads me to ask the question, what was the difference between your square Super Premium Sign and my rectangular Premium Sign? Were they producing 3 grades of gas at the time of the sign usage or is your square Super Premium of a different time than my rectangular Premium sign?
