By far the most exciting card in baseball history (to me), is the 1916 ZEENUT Jimmy Claxton card. First ever African-American featured on a baseball card, with a cool story on how it all happened. What makes this extra special to me is that he was born and raised in a small mining town which is the same place that I live in BC, Canada. I would love to own a copy of this card, but the high price tag may keep it from ever happening. If you do not know the story, here is a neat article:

Edit- I cheated and mis read the OP.. clearly this card does not fit into the designated time period... I refuse to delete my comment though as the card is too awesome.
