I didn't attend the 2015 National, but a friend of mine did. I asked him to try and track down any Andrew McCutchen exclusives while attending. Unfortunately he is a terrible friend and failed me. That forced my hand to try the world wide web and track them down.
Shortly after the convention, this cracked ice /25 Prizm National VIP exclusive popped up for a B-I-N of $10 delivered. It was a little more than I would have liked, but at the same time reasonable enough that I chose to pull the trigger. I'm still on the prowl for the Allen & Ginter die cut of Cutch along with some other parallels of this Panini card.
