I've never seen it before either...
I think it is strange that a promo copy of whatever release comes without ANY information on the sleeve.
Secondly (or third if you count that I've never seen this before ;-) I find it very strange that the tekst 'for promotional use only' or the equevalent is not on the disc.
Still, I also found this a 'nice' item and I am not convinced yet that it is not genuine...
Where's Ferdy?! ;-)
The disc is the common Elektra release No E 45297, see Andy's page link
The sleeve looks strange because it says A Night At The Opera and not BoRhap/IILWMC.
