You can see that the front also says "2013 National VIP". This card was given away at the National Convention last summer in Rosemont. Panini made five of each of the Prizm base for the VIP set. Mine is 2/5.
The best part was the price....for this /5 card, I had to pay 99 cents.
This is the sixth version of the card. I've also got the base, red, green, refractor, and cracked ice.
Take a peak at the mini-rainbow.
