Looks Like I Bought A Book With Stolen Art

I don't know for sure yet, but according to THIS thread on RPG.net, it looks like the PDF of the unofficial 6th Edition Tunnels and Trolls rulebook that I purchased from DriveThruRPG used a piece of art without the authorization of the artist.

Not only that, it looks like James Shipman and Outlaw Press have done this multiple times with other products. If this is true, this sucks and I am sorry that I supported them with my purchase. Uggh...

UPDATE: It looks like the offending books (including the one that I purchased) have been removed. I will take that as validation of the accusations...

Tunnels & Trolls 6th Edition

5th Edition Tunnels & Trolls is one of my guilty gaming pleasures. Even with all of its warts, the game still brings a smile to my face. Years ago, I undertook the task of 'fixing' some of the things that I didn't like about the game, including multiplying attributes for non-humans, using strength to power spells, etc. but I never finished.

Now I have stumbled across an unofficial Tunnels & Trolls 6th Edition of the game on Lulu that looks like it has done the work for me. Is anyone familiar with it? I want to know more before I burn $16.00...
