Wow, good eye. Were our positions reversed, I doubt that I would have made the connection. I wanted an image that showed more of the librarian's body, but could not find one. Seeing the stack of books would probably be enough for most people to get the idea, even if they didn't know the image's origin. On the other hand, this version does give it more of an air of mystery.

Did you like the movie? I did, and I even wrote my thoughts on MirrorMask in LJ awhile back.
