Original unopened rack pack from the 1960 Topps baseball second series housing three cello packs with twelve cards each for a total of thirty-six cards. The three individual cello packs are tightly sealed! There is the possibility that within this pack are high-grade examples of second-series cards, which most notably includes the #148 Carl Yastrzemski rookie card and #160 Rival All-Stars (Boyer/Mantle). This pack comes shrink-wrapped by Baseball Card Exchange and is one of only a handful of complete rack packs from this set that survives today. It originates from one of the hobby's most famous finds - Alan "Mr. Mint" Rosen's Jessup, Maryland, discovery of unopened material. Awesome original rack pack from the very popular 1960 Topps set!
