The most obvious and impossible to miss nod is Tony Stark's father, Howard Stark, and his heavy involvement in Captain America: The First Avenger's story. The biggest surprise, however, is at his fair when we spot the Human Torch in a display case. No, not Johnny Storm; we're talking about the original, John Hammond. We have no idea if this was the actual android or just a model, but it was awesome to see a nod to the WWII character that debuted in Marvel Comics #1.
