The art by Clyde Caldwell (identified in this question) that was featured on the cover of both the Genesis CRPG Warriors of Eternal Sun and the AD&D sourcebook The Book of Lairs is an excerpt from a larger poster.
I'm trying to track down an image of the full original painting. I know it exists because I once saw (a couple decades ago... OMG) the full poster in one of those huge "the art of AD&D-ish" coffee table art books, and even a picture of someone with the full artwork tattoed on his back.
Since the answer by @SevenSidedDie on the original question, I have searched to no avail for a digital or physical image of the original, so again, help a fellow AD&D geek out. Thanks.
Where can I find the full Clyde Caldwell artwork that appears on these covers?
