This is the case hit from 2007 UD Masterpieces that I traded away my Troy Tulowitzki Exquisite Rookies autogamer in order to get. Don't worry, I didn't get ripped off. I also got a Nate McLouth UD Clear Path to Greatness red ink signature, numbered 13/35.
The Martinez auto is very cool, though. It measures 5x7, and came in the top-loader, too, so now I don't have to buy that as well. It is an on-card auto, which is more than I can say for the Tulo or the McLouth. This is certainly one of the centerpieces of my collection, now.
