International Iron Man, issue #1, written by Brian Michael Bendis with art by Alex Maleev. I think the most important thing we can take away from this issue is that Tony Stark tried to cosplay as Sam Winchester* his entire time at Cambridge University, which I must compliment him on because he even got the problematic love-life thing down.
The overarching plotline for the series looks like it will be Tony trying to find out who his real father is (scandalous!), but this issue mostly takes place in the past—twenty years ago—when Tony was attending college in London. (Spoiler: he meets a chick at a party.)
Cool artwork on both the inside of the issue and on the cover. Read for the moose hair* and a meet-my-parents dinner date that went very well.
*Supernatural references, haha sorry
