Jason Sholtis and John Larrey are two artists whose work has graced the pages of both Knockspell and Fight On! magazines. I didn't realize that they have a joint blog (Mr. Larrey apparently doesn't use the internet) -- but I discovered it yesterday. If you're a fan of traditional pen and ink fantasy drawing, you will really enjoy their work.
One of the things I like about their art is that you can often faintly see the "player desperately rolling dice" behind what's happening to the characters in these illustrations.
