Perhaps the most footnoted item in the history of comics has been the full title of the organization S.H.I.E.L.D. Traditionally, when a character would pronounce SHIELD as a word of dialogue, the footnote would spell out that the six letters stood for Supreme Headquarters International Espionage Law-Enforcement Division.
Defenders #9 turned the convention on its ear. Here, Dr. Strange stated the full name of the organization in a conversation with Nick Fury, and editor Mark Paniccia placed the acronym S.H.I.E.L.D. in a footnote.
