OMG, OMG, OMG! San Diego Comic Con starts tomorrow but we’re already starting to see some of the nerd goodness leak onto the web and today we got a glimpse at some posters Marvel will be giving out at the show featuring AWESOME concept art from the upcoming films based on Captain America & Thor. Although I’m trying to remain grounded on my expectations for these films, this stuff makes it kind of hard to not get excited about these productions. Every year I regret not jumping on getting tickets for Comic Con before they sell out and this year is no different. Check out the full res versions after the jump and be sure to return this week as we’ll be updating all the cool stuff from the show here on Dumb Drum. [Images via Yahoo!]
