These are from a pack of the 2012 Rittenhouse Marvel Greatest Heroes trading cards. Five cards came in the pack. This Loki Villains insert (1:6 packs) is my favorite of the pack. I really like the art and simplicity of the card. The art on the base cards is pretty nice as well. The Ant-Man and Hawkeye cards harken back to some good classic looks. The backs are simple but ok. Definitely a set I'd look at getting more cards from. As always I would have liked to see more than five cards but this is definitely the trend with these cards.
