The new Indiana Jones Heritage trading cards from Topps also include sketch cards from a huge variety of artists. Patrick Schoenmaker posted his sketch cards at his blog and they're fantastic. There's apparently one sketch card in every 54 packs, but I wish all of the cards in the set were sketch cards. Link to Schoenmaker's site, Link to Topps (via Drawn!)
UPDATE: Lucasfilm's Bonnie Burton writes, "On Starwars.com, I've been interviewing the artists who are making these great Indy Sketch cards." Link
