In the early 90's a set of Dark Sun art prints were given to game store owners to promote the unique art of Dark Sun. We got a set of the prints and have scanned them for your pleasure.
Athas.org has interviewed Dark Sun creator Tim Brown about his new multi-media endeavor, the Dragon Kings Project.
Dark Sun creator Tim Brown has teamed up with original Dark Sun artist, Brom, to create a new fantasy rpg universe called Dragon Kings. Brown calls the world of Khitus his spiritual successor to Dark Sun
The Dragon Kings game will include a progressive rock CD, an art-intensive ‘album’ or ‘concert’ style book that expands heavily on each song (with lyrics, more stories, maps, specific art, etc.), and a hardbound game book. No release date yet.
For a massive book of his art:
"This Brom hardcover art book will be the largest, most comprehensive retrospective ever published on this renowned dark fantasy artist. "
Take a look at the kickstarter. There are a couple of levels for signed prints and sketches, if you're interested in that. It's already funded, with well over a month to go. Book delivery set for June 2013, about 10 months from now.
