Best D&D Artwork?

We all know that D&D has had a lot of different artists and art styles over the years. Some pieces have been pretty bloody awful. Others have actually been pretty damn good. What, in your opinions, are the best pieces of artwork to come out of D&D? Any edition, any piece - race, character, class, landscape, whatever. If it was in a D&D book or an issue of Dragon/Dungeon, it's fair game.
