Trivia
- Green Arrow and Black Canary were last seen in Action Comics #458 last year.
- In "Rainbows of Doom," Black Canary tries to disguise herself as a new entrant into the vertical bars competition by wearing a brunette wig over her blonde Black Canary wig, a red shirt in lieu of her usual leather jacket, and athletic slippers, in order to catch the Rainbow Archer. Canary comments on the impractical difficulty of wearing two wigs over one another and managing to keep them both convincingly in place during the competition, but it defies all explanation how Canary was concealing her knee-high boots under the ankle-high slippers of her disguise once she discards the latter.
- In "Explosion In a Small Town," the Vigilante technically fails to exonerate the sheriff of the town, since the actual perpetrator of the bombing run commits suicide in the last explosion. With the real criminal dead, it would also have logically become considerably more difficult to establish the sheriff's innocence, since there would be nothing to go upon but Vigilante's word and possible circumstantial evidence that the former sheriff of the town was the true bomber. However, because the villain is dead by the story's end and the bombing spree has ended, it is treated as a victory by the writer.
- In "Jeopardy-- Times Two," Wonder Woman defeats the Nazi saboteurs by tossing them into the Lincoln Memorial, apparently unconcerned of potential structural damages that this act could have caused.
