I do think the Orange Cow logo should make an appearance somewhere, though, out of respect to ocpmovie's fine work. But I agree that it looks funny on the spine. Maybe a very small one on the back somewhere, near all the other logos? Or above the Hyperspace logo, maybe, very small? Somewhere unobtrusive, yet still present.
Oh, one minor wording technicality: the blurb starts out "...a second production was underway/This is Return of the Ewok..." probably should read "This was Return of the Ewok".
But otherwise, I'd be happy to print that one out and put it on my shelf. Not that my JediSluggo cover is bad right now, but like he said, it was just a quick sketch.
