You are bidding on the original Series 1 Center Middle checklist and puzzle piece card. This is from the 1973 Gadzooka Gum puzzle. This puzzle is overall in Excellent Plus to Near Mint Minus condition (EX+ to NM-). None of the checklists on the backs of these third series cards have been marked. There are no visible creases, bends, rips or folds. This is a great way to track your collection as all of the card in this 1st 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 set, this is an awesome puzzle to add to your original Series 1 collection. These puzzle sets are getting tough to find as many of the pieces were discarded in the 1970s.
