Consider yourself officially made, Dave. Marvel Studios president and super-producer Kevin Feige used his third tweet ever (the other seven are retweets) to thank current Late Show and former Late Night host David Letterman for his 33 years of broadcast magic. Specifically, he shared the cover of Avengers issue #239 with Black Widow, Hawkeye, Black Panther, Beast, and the mostly-forgotten Wonder Man in 1984.
But that was just Letterman’s first appearance in the Marvel universe. He also popped up (in various ways) in issues of Amazing Spider-Man, West Coast Avengers, Iron Man, and others.
