UPDATE: The above clean look at the image comes via ComicBookMovie.com.
The following poster for The Avengers was posted by ESQ. (via Latino Review) from the floor of the Licensing International Expo 2011 at the Mandalay Bay Convention Center in Las Vegas. It's a little blurry and I had to crop it and center it to make it look a little better, but I wouldn't be surprised, with Comic Con coming at the end of July, if this is just the start of things and we'll get something much better very soon.
Featured in the image is the Hulk as will be played by Mark Ruffalo, Hawkeye (Jeremy Renner), Thor (Chris Hemsworth), Black Widow (Scarlett Johansson), Captain America (Chris Evans) and Iron Man (Robert Downey Jr.). Joss Whedon is directing The Avengers, which is shooting now, for a May 4, 2012 release.
