Right, so I've had this for ages and have used it every now and again when I forget what's on it but most of the time, it's just an ornament in my CD rack. I've picked it up today and taken a little closer look at the insert and the signature, that I originally thought was just a print, is actually a genuine autograph. I have done some research into it via google and found that there were signed copies distributed but what I can't find is how many.

Is it a collector's item or were they signed by the shelf-load?

Does anyone else own a signed copy and, if so, when and where did you get it? Any info anybody can offer would be much appreciated.
