You may not be surprised to learn that most people in the comic business grew up reading comic books. However, you might be interested in knowing what they were reading. Here’s a look at “Famous Fanmail”!
Peter Sanderson isn’t a comics writer but he’s certainly a Marvel historian. He’s helped write the Official Handbook of the Marvel Universe along with several other guide books. He got a letter printed in Fantastic Four #200 (cover date: November 1978), commenting on the issue where Doctor Doom revealed his face to the Fantastic Four. The response seems to indicate a reason why the FF weren’t surprised to see his face but I don’t remember this being followed up on. Must be one of those famous dangling plotlines.
