I drew this in 2005 for a Northern Crown adventure module called Isle of the Judge that was never published. It was a mix of Salem Witch Trials and HPL goodness. Think: Shadowe over Innsmouthe.
I still like the illustration, though. This was done with black and blue colored pencils and a bit of watercolor. When I'm drawing something that's going to be reproduced in grayscale, I often go the monochrome route, but the originals still have a cool vibe of their own -- it all hangs together coherently.
