Teaser Poster for Episode III?

According to Cinescape: "TheForce.net has published what looks like an authentic image of the first promotional theatrical banner for STAR WARS, EPISODE III: REVENGE OF THE SITH. If it's a fake, it's a very nicely done fake. The banner shows the silhouette of Darth Vader standing in what appears to be a corridor that could easily be inside a Star Destroyer or even the Death Star: dark, with a reflective floor and background lights on the walls. Mist swirls around the helmet of Vader, but instead of seeing the breathing apparatus of the Dark Lord, we instead can make out the shaded figure of Anakin Skywalker in his Jedi robes."
