This 1984 Fleer Baseball Cello Pack contains 28 cards. The 84 Fleer set was known for the Don Mattingly and Darryl Strawberry rookie cards, but also contained many other stars and HOFers (Ripken, Brett, Rose, Yaz, Bench, Schmidt, Ryan, Gwynn, Boggs, Yount, Sandberg and Trammell). This particular pack came from a box in a Probstein card auction. These packs are now 41 years old!
