The offical Avengers movie poster was released along with it's teaser trailer. As you may know the whole Avengers cast was assembled on stage at this years Comic-Con. They all added you editions such as Mark Ruffalo replaceing Ed Norton as the Hullk, and Jeremy Renner playing Hawkeye. Other then that it's pretty much just Robert Downey Jr( Iron Man), Scarlett Johansson (Black Widow), Samuel L. Jackson (Nick Fury), Chris Evans (Captain America), Chris Hemsworth (Thor), Don Cheadle (War Machine), and Clark Gregg (Agent Coulson).
It still hasn't been announced whether Wasp and Antman will be in the film but that should be announced when the film nears filming. As for the trailer it shows nothing from the film but it does manage to get you excited.
So I guess this fan-made poster was a little off.
