An artist who worked on the original kid show version of "He-Man and the Masters of the Universe" by Filmation back in the early 1980s and happened to notice that they were throwing away some pencil renders of their backgrounds used in the show and saved them.
They are, IMHO, old school AWESOME. Being rendered in blue makes them very reminiscent of the artwork from the classic AD&D modules and seem very appropriate for use as visual aids in any D&D game. But don't take my word for it, look for yourself:
You can find the whole collection that he's posted so far at his website. You can also read about his history with Filmation, if that sort of thing interests you (which, for me, it does).
