Look at this eBay Ireland listing. Apparently, one version of the game came shrinkwrapped as disc+manual only. However the one you posted has "promo" printed in the spine, and look at where the EAN is supposed to be - it says "Promotional Copy".
This may have come with specific Xbox models, possibly only in some regions. Or it might've been distributed to retailers or in trade shows. Who knows.
If the artwork isn't fake (as in, someone printed it) it's a valid alternate issue and it deserves a listing.
