I have part 2, its in an Alien Magazine issue (vol.2#10 i think). The oversized format of the magazine was magical when paired with Den Beauvais' art. I do wish it was in color though.
However i learned the hard way that the first part was actually a seperate mini issue originally sold with issue vol.2#9. I have yet to find a copy of the part one mini comic
I have emailed DH detailing how disappointed I was that it wasn't included with the Fancy Pants Hardcover. I did get a very nice reply from them though, ill see if I can find and post it.
Edit: found it
