i don’t think this necessarily makes it a bootleg. it could just mean that instead of numbering each cd of this \"limited\" release individually, they faked the numbers, by putting the same number on each cd.
it could also mean that someone scanned his copy and made a couple of extra copies (fakes), now all with the same number. but i find this less likely: although this cd is fairly hard to find, i don’t think there’s a lot to be made in making fake copies of it.
does anyone own this release with a different number on the cd?
