Oh great. Yet another tease for all of us who can’t make it out to San Diego. I’m sure they’ll be reasonably priced on eBay in the weeks to come…

Headed to San Diego Comic-Con? Don’t miss out on what are sure to be some of the hottest items of the convention, these posters featuring concept art from Marvel’s “Avengers: Age of Ultron,” in theaters May 1, 2015!
Make sure to stop by the Marvel booth, #2329, to pick up these free posters while supplies last! These two posters are only available during Preview Night, while supplies last. Today’s posters feature artwork of Iron Man by Ryan Meinerding as well as a poster by Andy Park of Scarlet Witch.

Cool looking posters, I seen the ones with Cap and Widow today. Tomorrow will probably be Thor and Hulk, and then Quicksilver and just maybe the Vision, the last one is probably unlikely though haha.
You forgot Hawkeye 😉
