Up for purchase is a 1971 Season Strat-O-Matic Football Kansas City Chiefs team set.  It is from the 1971 Season 6 Pack Set which was originally issued by the game company in 2013, and is now out of print.  It is a complete set of 18 cards in Near Mint condition.  I am not the original owner of the set, but the cards appears to have been little-used or unused by the previous owner.  There is a 1/2 inch slight indentation just below the top edge of the offensive/defensive ratings card (pictured), but otherwise no significant flaws noted.  There is neither writing nor marks on any of the cards.
