Wow thank you for posting that! It's actually pretty funny to imagine Steve at a con, being surrounded by all these people dressed up as people he works with. I actually did know about Steve's job as an artist for Captain America comics, but I'd never heard of Tony cosplaying as himself? How does that work? Do people just assume he's a normal guy and totally not the real superhero that he looks exactly like?
Oh, my dear anon, please allow me to tell you about Iron Man v1 #72. You can tell even before you read it that it is THE BEST COMIC because its title is “Convention of Fear!” with an exclamation point and everything. (Okay, it’s not actually the best comic, but it’s pretty funny.) And, yes, people assume he’s just a regular guy and totally not the real Iron Man.
