Thanks to the wonderful WW readers out there, I learned that the missing player was Shawon Dunston.
Now, thanks to a very generous WW reader, I have the missing card!
Reader Kevin emailed me and said that the card was a part of a lot of Cubs card that he had picked up. He also asked if I wanted it. My answer....YES!!!!!!!!!!!!!!
He dropped the card in the mail, the USPS did their thing, and now I can scratch this off of my most wanted list. Thank you Kevin!!
When I was on the hunt for the card I made my own version...
...which isn't too far from the real thing.
