Were you a little let down by that Avengers teaser trailer that came out of Comic-Con? Sure, the logo looked cool, and the voice-over was dramatic, but where were the Avengers themselves? Turns out if you wanted to see those heroes in action, you had to head back to 1952.
YouTube user whoiseyevan managed to dig up this trailer created a decade before The Avengers were even born. Amazing, huh?
To which we can only add—Excelsior!
