That's our first official look at Captain America in the movie, who's sporting a rather rugged beard and weary expression. No surprise there considering what he's been through post-Civil War. Black Widow gets a slight makeover and we can see more of teenage Groot!  

Here's all three of the SDCC exclusives lined up:
