You are bidding on the original Series 5 checklists and puzzle piece cards from the 1974 Big Baddy puzzle.  This puzzle is overall in Very Good Plus to Excellent (VG+ to EX) Condition. None of the checklists on the backs of these fifth series cards have been marked. The cards have the usual gum stains and very slightly rounded corners on these vintage cards. None of the cards have visible creases and there are no hard bends or folds. This is a great way to track your collection as all of the card in this 5th series are listed on the backs. This puzzle displays very nicely and most of the small flaws go unnoticed. If you are not looking for Mint or Pristine set, this is an awesome puzzle to add to your original Series 5 collection. These puzzle sets are getting tough to find as many of the pieces were discarded in the 1970s. Check out the picture of the actual cards and let me know if you have any specific questions on these 9 puzzle cards.
