WCS 94 has many license holders. I can't see it ever having the sideart done. I'm starting a restoration, and the first thing I noticed was that it has the standard Bally/Williams decal and then a FIFA "official" logo decal placed over the top of the sideart. So FIFA would not allow their logo on any reproduction without permission. We know how "organized" FIFA are
Under the "right to restore", you are permitted to recreate ANY artwork on the game as long as it is for your game and only a single copy can be reproduced.
