While not a baseball card, I have something similar. I have a Ku Klux Klan pocket knife with a clansman featured on the side. It's a very cool knife that was in my grandfather's extensive collection, although it feels a bit evil just holding it. When he died, I took a couple of his knives to include the KKK one since it struck me as being a piece of history. I've thought about selling it once or twice, but I'm not even sure Ebay would let it be be listed and what comments I would get. Maybe someday I'll use it to teach my kids about the dark side of our history...
Take Care,
Geno
