My nephew-in-law Dusty Leggs reconciles the seeming conflict of silliness and seriousness between his love for comic books and a respect for historical figures.
I don't really read comic books or graphic novels these days, but in my youth I was a big fan of Archie. Some of the Archie comics I read were published by Spire Christian Comics - in these comics, Archie and most of his friends are Christians. I believe I still have some of the comics at my parents' home - I haven't looked at them in years, but I know for sure that I have this and this.
UPDATE: I want to qualify the first sentence by saying I believe that (1) graphic novels can touch upon serious issues and (2) some historical figures were downright silly, or at least they dressed that way.
