Nintendo felt it was burned in the early 1990s when it licensed Super Mario and The Legend of Zelda out to Hollywood for film and animation projects and didn't like the eventual end result, but for a while there the company really was trying to make it work. 1980s powerhouse DIC turned both games into the animated/live-action hybrid syndication smash The Super Mario Bros. Super Show in 1989 and Nintendo Power was there to promote it. After all, what better way to spread awareness of the new program than through the game publisher's own in-house publicity publication? Over on Twitter, @VGArt&Tidbits has a scan of the single-page tease from the July/August 1989 issue.

The main piece of art doesn't represent the visual style used on the cartoon at all, but I remember seeing it on licensed products such as TV trays and notebooks back in the old days, so I don't know if it's just an unrelated piece of art used here as filler or cartoon concept art that changed direction. Either way, it's an interesting look into the past. Who's that white-haired Mario ancestor in the photo on the wall?
