Id agree (then again, I WOULD... *points to devil of despair*). But im not exactly sure if that is the case, or if Im just making it up.
I believe the kickstarter reward cards that have backer art on it have two names in the artist credit. While I certainly did not draw the Devil of Despair, I did give the art direction. As such, my name is next to Martins. So that leads me to believe that any card with two names are kickstarter art cards. The exception to this is Core 2013 cards with Jordan Beeston and some other girls name. They were both uni students working at Lightmare as part of work experience. Jordan drew, and the girl animated.
Jordan now animates his own cards, and has done a few more pieces for Lightmare.
He also does work for the new game, Chromancer (I know this, because I hooked him up with the gig!)
