Ok, here's an idea for a fun contest. I post a section from a comic cover and you guys try and guess what cover it's from.Whoever guesses correctly, gets to post a portion of a cover themselves, and we all get to guess. It's not good form to post a very tiny part of the cover, as it makes the contest too difficult.
Here's my starter - a clue is that this particular cover (like all of mine) is from the Silver-Age.
Here is the 5th one, which illustrates Hoy's point that there was a Wonder Woman cover for every theme.
Here is Lois only one issue after marrying Bruce Wayne. Talk about fickle.
