This was the only way I could achieve this rank. I made some Magnetic Signs for "Miss Tillie" and will use them in parades and shows only, as they can scratch the finish if left on for any time. It is also a good idea to wax the back of the magnetic material and ALWAYS clean the door first.
I just wonder if a 1930 Chief of Police would have had Whitewalls? I don't think so as our country was in the midst of the Great Depression. But this is a "Fun Car" anyway, 83 years later.
