I know the answer is there a prize?
You could have requested your number on the jacket at the time...all done thru Molly that ran the Buick clothing line.
Years ago I bought up all the remaining GNX jackets from Molly mostly where small sizes. The key thing with Mollys clothing line is they have his label in it. I also bought up all the unclaimed numbered GNX books roughly 100 were never claimed of the 547.
I think way back when we were selling the small GNX jackets for like $35 or $50 each....
