I share some people's distaste for the new IDW covers. They do, however, include certain lesser known images by Dave that deserve recognition. They also fit in with the name of the set, Dave Stevens' Covers, so to be totally complete, the set should include those books. I also think that the back covers are pretty much no-brainers, those are Dave's covers.
I'm curious, what do people think here about including the "Cult Movie" covers Dave did? They're not drawings, but they are his art, and include his "DS" signature.
Another thing: the ARK magazine has no place in the registry, as far as I can tell, it's not a cover by Dave, and is in the same category as the Who's Who books.
