Even as a kid, I suspected most of the letters in DC comics were bogus. They were so transparent. "Have you ever published a story where Superman meets one of the famous strongmen of history?" "You're in luck. In the October issue of ACTION COMICS, we present a new story, 'Lois Lane's Super-Suitors,' where the Man of Steel has to deal with Lois being wooed by not just Hercules but also Samson." It seems every column had a convenient letter asking about a story about to be published. The letters weren't signed I. M. Phony, but...
Stan Lee's answers to letters, on the other hand, were breezy and irreverent. To a statement that a fan bought DAREDEVIL only to see how many mistakes were in it, Stan might reply, "We don't care if you buy our comics so you can cut out paper dolls, as long as you keep buying them."
