Just wow! He even has a www.gofundme.com/Mystara page to pay an artist to replace the filler art, which is of course being done strictly as a fan and not-for-profit.
Using my GoogleFu, I found a pdf version: Clicky, clicky. And, it's version 5, which I believe is the latest version. The version in the op above link is version 4.
Two threads on this now.
I mean, it deserves multiple "looky here!" But it might be easiest to have them condense into one so all the people can see all the things in one place?
