72 stickers on 44 panels. As most panels have 3 or more stickers, there is clearly duplication. While the hobby is now focused on the cards that were included to reinforce the packs, at the time of initial sale, the stickers were the focus (if you've ever seen a pack or wrapper, it encourages the buyer to collect all 72 stickers and doesn't even mention the card). That being said, it is kind of interesting/amusing that from 1970 to 1971, they changed the set name, the packaging, and the card in the back- but the stickers are exactly the same.Primary condition issue is toning- very typical for stickers this age.
