The 1957 Topps set was the very first pack of cards I ever bought. I remember buying both 5 cent packs as well as penny packs. I was not yet 7 when I was told by a friend that the new baseball cards were in at stores at each end of my block. Growing up just south of Pittsburgh, the Pirates were our home team to root for. I can't say it was the first pack but if not in one of the first couple packs I bought the first Pirate's card I got was #24, Bill Mazeroski who I decided would be the player I would root for. Great childhood memories of a great set of cards.
