EDIT: If you're playing in my Greyhawk campaign, please don't look at these maps!
Good news for fans of the Castle of the Mad Archmage!
Our erstwhile cartographer, Joe Bardales, has come up with a comprehensive set of poster maps covering levels 2-13 of the dungeon! Here's just a sample of the wonderfulness that awaits your downloading pleasure (click to embiggen):
You can download a .zip file with the whole kit and kaboodle --> HERE <--
Of course, the individual 8.5"x11" maps are already included in the regular .pdf file of Castle of the Mad Archmage, but these poster maps are really exceptional, and add a lot to the feeling that each level is a cohesive whole.
