The above Royal sign is Fake! As far as the Super, I have only seen two and they are both in collections in California? I have all the rest, including the Diesel,but have not been lucky enough to find a Super? Maybe they were only in California.. I have only had my hands on three Diesel plates, so it too is rare, last one I saw sell brought $1500.
Wanted: Conoco, Marland, Eason, Cliff Brice, Speedway and Oval E stuff!
