Aaron McConnell and Lee Moyer got four (maybe five) pieces from 13th Age into the show and are also going to be selling prints. I believe they are pieces no one has seen yet, striking work at a great size.
The line-up of artists showing work is amazing. I'm excited for this show, especially since I rarely get to spend enough time in the art hall at GenCon. And yesterday I got to contribute a small wall-blurb on fantasy art from a game designer's perspective. Make time to visit.
