Wizard vs. Demon Dog - OSRIC Art
Well actually this is a Glabrezu, a type of demon in the Dungeons and Dragons game. Pretty bad dudes and unless you are Gandalf or similar stature, not something you'd care to tangle with. I always rather liked this piece. Undead and Demons/Devils were always some of my favourites because of their variety, and there were no moral implications for taking these suckers out - they are some seriously bad dudes. Happy gaming!
