My favorite beater and on some level card, is what I lovingly call Exorcist Bill Dahlen, due to the incredibly well-placed ink stain.
I'm a big fan of cards that have lived a good life. Funny story here is that the first time I saw the card, it was paired with a very rough Brown Hindu Harry Bay before I was certain I was going to collect the Southern Leaguers. I ended up as the despondent underbidder on the card, thinking I would never see Exorcist Bill Dahlen again.
Fortunately, the winner of the lot was primarily concerned with the Brown Hindu Bay and four weeks later, Exorcist Bill Dahlen has arrived at his final resting place in my collection.
