[2][3] The year before there was a similar 1939 New York World's Fair Comics featuring Superman but without Batman and Robin because Bob Kane and Bill Finger had not yet created them.

The series was initially a 96-page quarterly anthology, featuring various DC characters – always including Superman and Batman – in separate stories.

[4] Comics historian Les Daniels noted that "pairing Superman and Batman made sense financially, since the two were DC's most popular heroes".

[9] The story "The Clash of Cape and Cowl", by writer Edmond Hamilton and artist Curt Swan, in World's Finest Comics #153 (Nov. 1965) is the source of an Internet meme in which Batman slaps Robin.

[10] Noted Batman artist Neal Adams first drew the character in an interior story in "The Superman-Batman Revenge Squads" in issue #175 (May 1968).

[29] Haney frequently disregarded continuity by scripting stories which contradicted DC's canon or by writing major heroes in an out-of-character fashion.

Issue #250 (April–May 1978) combined Superman and Batman with the Green Arrow, the Black Canary, and Wonder Woman into the World's Finest Team in a 56-page story.

This double-sized anniversary issue was a "jam" featuring a story by writers David Anthony Kraft, Mike W. Barr, and Marv Wolfman with art by Ross Andru, Mark Texeira, Sal Amendola, and George Pérez.
