Wow, that's pretty cool. I'll stick with my ultra-rare copy that has the dustjacket that was cut too short and no Whispers Press on the spine of the book. At least I think it's ultra-rare, FPW mentioned something about this a while back and I was blown away to find that my copy was like that. Just to think, I got it on E-bay a long time ago for around $30.

I guess it can't be considered "ultra-rare" if the collecting public doesn't even know an "edition" like this exists.
