Wow not to long ago there was a bunch on ebay .. that's odd they all disappeared.
The alternative is to take the image from this post http://forums.arcade-museum.com/showpost.php?p=2327855&postcount=1 find a digital artists like the guys over at HyperSpin and get them to blow it up to 1:1 and clean it up. Then take it to a print shop or send it to one of the guys on here to get printed. Not the cheapest route.
For the control panel I have not seen any NOS for this game, not to say someone doesn't have it squirreled away for a rainy day. On the other hand I always see plenty of people selling the CP from a stripped down machine. This one looks kinda rough http://www.ebay.com/itm/Tekken-Cont...432969?hash=item211c94c689:g:k10AAOSwJQdXC6fD . I think finding the source art to have an artist repro this one would be a pain, but that's an alternative also.
