Beautiful unopened 1967 Topps cello pack featuring Tommy Harper on the front. The back of the pack is covered with some type of white paper or cardboard making the card on the reverse impossible to see. Graded NM-MT 8 and encapsulated by PSA the pack appears tightly wrapped and the cards in outstanding condition. Unopened material is becoming more scarce and valuable by the day as collectors continue to seek out more and more tough-to-find material (and others seek out unopened packs to open looking for buried treasure). Could this pack contain a Seaver rookie? A Mantle? A Carew rookie? Perhaps!
