The image comes from BleedingCool, and will apparently grace the cover of comic collection titled The Road to The Avengers, which will include Marvel Studios movie continuity stories I Am Iron Man, Iron Man Security Measures, Iron Man 2: Public Identity, Iron Man 2: Agents Of SHIELD and Captain America: First Vengeance. Their report also includes several other collections intended to both capitalize on and build awareness of The Avengers.
The group appears to be posted up on the exterior of the SHIELD helicarrier, judging by all the clouds and whatnot. We've seen plenty of Captain America's new outfit, but based on this image, it looks like Tony Stark's Iron Man armor might get a little style upgrade as well, with some more gold on his chest and steely femur-guards.
From left to right, you're looking at Scarlett Johansson Black Widow (Scarlett Johansson), Nick Fury (Samuel L. Jackson), Iron Man (Robert Downey Jr.), the Incredible Hulk (Mark Ruffalo), Captain America (Chris Evans), Thor (Chris Hemsworth), and Hawkeye (Jeremy Renner).
Production on the film is nearing the home stretch under writer-director Joss Whedon, finishing up its time in Cleveland soon before wrapping up completely in New York.
The Avengers throw down theatrically on May 4, 2012.
