Marvel has released these two great new poster art designs from Joss Whedon's The Avengers, showing off the new costumes of Black Widow and Hawkeye. To see the two previous character posters of Iron Man and Captain America, click here. The art comes from Ryan Meinerding and Charlie Wen. I gotta say, I like Hawkeye's costume. Apparently the posters are being given away at the Marvel Booth at Comic-Con. What do you think?
