I'm not buying this, and I don't think most fans (of NIN or Mills) will be either - which works out well since there are only 2000 copies - but at least check out the documentary about the project before assigning a value to the work:
Anyway, I think the artwork is great and would definitely like to see the book at some point. I think the artwork goes well with the album, although I don't think album art necessarily has to
match the album. I think it's fine if the art changes how you hear the music.
Do you have a link to that advertising? Because that sounds like a very simplistic interpretation of what was said about the album before it came out (e.g.
this), and not something that was obviously present in the advertising.
