"Captain America’s secret identity was a secret until that CAP run that you’re talking about in the early 2000s." Cap America Volume 1 #111 page 3 - Are you saying that Steranko's run isn't cannon anymore;-) or Stainless Steve's Avengers? - Avengers Volume 1 #107 page 17 the Space Phantom makes the whole world forget Caps identity to put his mind at rest so he could kill him, then resurrect him and be the recipient of the Visions brain patterns. Does this get me a No Prize? Am I showing my age?
I didn’t list out every dogleg where Cap’s identity was revealed to the world and then made secret again, as those periods cover a relatively short amount of time, and nobody remembers them anyway. Well, apart from you and I that is.
