These are my two Roberto Clemente cards (yeah, him again). My buddy Ronnie gave me the one on the left back in the 2nd grade (2nd graders rule). The one on the right is the reason that these cards made the list. It came in a pack of City Pride bread from Giant Eagle back in the day. If you don't remember City Pride bread, then you're not a 'Burgher. Its pretty much worthless, but not to a young Pittsburgh kid.
That pretty much completes the list for today. If I find more, then this might become an annual type of thing.
