Okay, false alarm. A little digging leads to information that it is “fake”. (Warning, Facebook, follow link at your own risk). It is, however, original art by Denis Loubet, the guy that did a lot of the actual Ultima box art, and it was meant to be the Ultima 7 box cover, before it was changed to the, IMHO, classy and timeless black one.
Somebody must then have translated the subtitle, for whatever reason.
