Quote: Until recently, only one Sky Skipper existed, and that was at Nintendo of America. The game was never actually released. A user in the UK got permission to have the artwork re-created to restore a cabinet he had purchased that had an actual Sky Skipper PCB (which had been converted to Popeye). Rich from This Old Game was kind enough to make a copy of the artwork for that second cabinet. I don't know that there are plans to actually make that artwork public or not. You can read that story here:
It would be nice if they would release the artwork. I don't see how it would hurt anyone. A cool journey for them. Nice to see they made a replica of the original.
