A few days ago someone posted one of these in a thread asking if it was official or not. Just wanted to post up that no, they're not.
The ones that have a team on each poster are Shinkiro's KoF'96 artwork with a flame pattern on the back. I think these originated either in NYC Chinatown or somewhere in Hong Kong. There's one for each team and I think Goenitz and Chizuru Kagura as well. Other posters done up like this include the MVS cover for King of Fighters '97 and a few others.
