Continuity with Earth-One

Continuity Similarities with Earth-1A and Earth-One
Writer E. Nelson Bridwell and the editors of the Super Friends (comic book) made frequent footnotes to events going on in the known DC Universe (Earth-One) comic books. What ended up happened is that fans realized that you could not fully merge the continuity, dubbed the SuperFriends Universe as Earth-1A.

What follows is a chronological unfolding of those references where they appeared.

(Rather than reference comic books with endnotes, we link them directly to DC Database).

This is a list of comics that take place within the universe known as Earth-1A, but are not part of the Superfriends comic book series. These are stories that are referenced in the comic book series, and so they therefore are part of the Superfriends canon, as well as the Earth-One canon.
