Last night, Marvel launched a trio of epic concept art Comic-Con posters for Ant-Man and Avengers: Age of Ultron, with the latter teasing a look at Iron Man and Scarlet Witch.

Now the studio has revealed the next two posters in the series, this time showing off Captain America (by Ryan Meinerding) and Black Widow (by Andy Park) in the battle against Ultron’s army. And if you look (not particularly) closely, you can see a mighty green arm in the corner of Black Widow’s.

Robert Downey, Jr., Chris Hemsworth, Chris Evans, Mark Ruffalo, and Scarlett Johansson take centre stage, joined by Elizabeth Olsen, Aaron Taylor-Johnson, Samuel L. Jackson, Jeremy Renner, James Spader, Paul Bettany, and Josh Brolin.

Joss Whedon is back behind the camera, directing from his own script.

Those at the convention can head over to the Marvel booth (#2329) to pick up your free copies of the posters. I’d hurry, because they won’t last long, and are set to only be available today.

Avengers: Age of Ultron will be released in 2D, 3D, and IMAX 3D on April 24th, 2015 in the UK, ahead of its May 1st release date in the US.
