If you do a search for "Darwin Barney 2010" only two cards are listed. I've had one of the two for a couple years...
It's taken a while, but I finally got my hands on the second one.
It too was put out by MultiAd Sports and is part of an Iowa Cubs team set. It's a good thing the company is called MultiAd and not MultiPictures because they used the same picture on both cards. They're a minor league company but they pulled the same lame stunt as the big league Topps.
Barney's All Star performance at Iowa in 2010 led to a mid-August callup to the Cubs. And from there his career took off....and more recently tanked.
