I remember being in charge of trophies for that event and putting together probably 50 trophies total. The class designation on the roof was done with press on letters as was the place, 1st, 2nd or 3rd, on the door. I can't remember if the letters were then clear coated...maybe. The die cast cars were available at the time in bulk (collectors items by now!) and the walnut base came from Athletic Supply via their trophy department. The dash plaques were ordered from one of the specialty suppliers and came with double back tape.
Thought you might enjoy seeing some more "Stuff" from the '70's.
