At one of the local card shows on Saturday, I picked up a couple of packs of cards, not sure exactly what they were. They were in the seller's dollar box, so knowledge wasn't vital to my purchase.
After opening one of them, I discovered that it was a set of some sort. A quick interwebz search found a link from Panini about the set. It was a giveaway at the Match 8, 2014 Dallas Stars game. That night, Mike Modano's number was retired at American Airlines Center.
The last card has a coupon on the back for 10% off from Panini.
