Check out this intense fan-made poster for Captain America: Civil War that was created by DeviantArt user AndrewSS7. It features Captain America and Iron Man in the heat of battle. This is what the artist had to say about his work:
"Marvel means only one thing: the sparks are back! A lot of sparks.
"Okay, here's a teaser poster for Captain America 3 movie which is gonna be based on the Civil War event. So, we'll have a fight between Iron Man and Cap. I went for a scene where the two superheroes confront each other (No idea how they are going to show this in the movie though. Sure it will be epic).
