Extremely rare and coveted unopened 5-cent pack from the first truly great baseball set and Mickey Mantle's rookie season! Graded EX-MT+ 6.5 by GAI and encapsulated in its protective holder, the pack appears very nice with small opening on the right side, although the cards look unaffected. What could lurk inside? Packs such as these were bursting with delicious slabs of cardboard so much tastier than the gum. Inside was the “true” Mickey Mantle rookie card and the “Honus Wagner Card” of the time.
