There is nothing better than getting a unexpected mail day and when that mail day is an Upper Deck NPN (no purchase necessary) mail day, you know it's going to be good. This particular one is from the 2013-2014 Fleer Retro basketball.
I love Retro and PMG's! Awesome NPN mail day!
Have you ever received an Upper Deck NPN mail day? What's the best card you have gotten?
