Here's a piece I did some time back for the OSRIC 2.0 hardback. OSRIC is pretty much a clone of Advanced Dungeons and Dragons 1st edition with the DM's guide, Player's handbook and monster manual all in one tome. I did most of the demons in the monster section and it was quite fun. I'll have to revisit this one I think. I like it for one of my earlier works, but it would be nice just to redo some of the early pieces. Cheers and happy gaming!
