I have a 1960's G I Joe air vest that I have never seen anywhere else, and it may be a prototype. I am not a G I Joe expert, but I still think this piece might be, if not unique, rare. Instead of being the normal orange air vest that says, "G. I. JOE AIR VEST U.S.A.F.", mine states in less bold wording simply,"u.s.a.f.". Could anyone inform me on this?
Thanks
