I've listed several vintage NFL football helmets on eBay that belonged to my cousins and I when we were kids.  These came right out of the attic of our late Aunt and Uncle - undisturbed for decades.

RAWLINGS U.S.A. - AIR-FLO - HNFL - SMALL.

Team:  BALTIMORE COLTS.

Overall very good but used condition.  Know that these have been played with during the legendary backyard football games we used to have as kids (late 60s / early 70s era) and do show scuffs, et al.  Please examine all LARGE images for condition.
