Well, I purchased two copies of GunBun #1 from Rabbit Valley comics. Total order cost about $20, so it wasn't cheap.

It contains about 36 interior pages of Gunbun, including one complete story with finished artwork (Shear Mayhem!), one complete story with unfinished artwork (untitled), one unfinished story fragment, and four Coco pinups by various. An unfinished, incomplete and unrelated story (FoxQuest) is also included, apparently as filler (5 pages).
In the lead story, an out-of-costume superhero catgirl tries to convince the crowd at the styling salon that she has bested a villainess, but the matron of the establishment knows better... and tells the story (in blow-by-blow fashion) of how Katrina was defeated when she tried to displace Coco GunBun as the local superheroine.
The front cover is nice, although I wish we could see more of her ears...
