on second thought, even tho it's not the 1st one I thought of, this one (62 issues later) embodies how I'm feeling about the world at the moment in the current political climate. . so changing my entry to stick with this one:
There are so many Golden Age Namor covers that fit this topic. I picked this one because I was wondering where he got that mallet.
There are so many that I have often wondered how readers of the time took that. Did they assume that growing to giant size was one of his abilities, and he just didn't happen to use in the issue they read, other than on the cover? Did they feel cheated because the comic turned out to be about a swimming fish-man, not a giant Nazi-crusher? Or did they get that the covers were symbolic? I'm pretty sure that many readers were confused.
