THE AVENGERS - 6 Fan-Made Minimalist Posters

Here's a fun collection of six minimalist posters for The Avengers.  The poster designs include simple designs for Captain America, Iron Man, Thor, Hawkeye and Black Widow.  

I tried finding the person who designed these posters but couldn't come up with anything. If you know who designed them please let us know so we can give credit to the artist.
