I thought I'd seen everything when it came to relic cards. I've seen:
Plus, let's not forget: Hair, Glove, Bone, Insect Exoskeleton, Stamp, Button, Coins, etc...
But I'd never seen a relic card quite like this until I found it at the Topeka card show this weekend. This is a piece of the Outfield Wall of Three Rivers Stadium that housed the Pirates from 1970 to 2000. Not quite a piece of the Berlin Wall but neat nonetheless.
