Yesterday you have seen two concept art posters of Robert Downey Jr.'s Iron Man and Chris Evans's Captain America for THE AVENGERS. In case you don't, you can check them out here.
Now there are two more concept art posters for you fans! This time they are Scarlett Johansson's Black Widow and Jeremy Renner's Hawkeye. (I must say looking at Renner's Hawkeye in a full costume mode is absolutely cool) Check them both below.
