I believe the Upper Deck card series MARVEL MASTERPIECES 2, for which I did roughly 200 sketch cards, is out in shops today...
Someone pointed me to a couple eBay auctions for cards I did, and my comic shop had a couple cases (I bought one pack, never seen the cards before... didn't get a sketch card... they're one card to a case)
You can learn more about the card series at Upper Deck's website
Get more info on my cards HERE
or view most in my DeviantArt gallery or HERE
Or here's a hand LINK for MM2 sketch cards on eBay!
