This card is now a prize in this weeks contest, I would say grand prize but it's winners choice so this may not go first. Anyway, it's a Bowman Sterling Matt Stafford Refractor RC serial #/199. Please put your guesses in the comments of the previous post so they'll all be grouped together.
I picked up a few other cards yesterday that I'm sure will make their way into another contest or two. Once again good luck.
