Topps got serious about cello packs in 1970, increasing them to 33 cards sandwiched around a stick of gum. This 1970 2nd series cello is a brick of beauty, graded PSA 8. Likely issued around the end of spring in 1970, it could contain high-grade examples of Reggie Jackson, Harmon Killebrew, or Thurman Munson's rookie card!
