curls has discovered some new photos. I'm putting them and the link to the source under a cut in case they could be spoilery.
Source If you click the source, it also has a hi-res photo of the domestic poster and Black Widow's break-out poster. There's also another picture, but since it's a scene from the trailer and nothing new, I didn't put it up. But still worth a look.
I just love that pic of Happy, personally. I don't know why, but he looks awesome and that briefcase looks awesome!
