Justice League (1960) #075 FN

1st appearance of Black Canary in Silver Age.

Green Arrow and Black Canary recall the tale of the Justice League of America's latest adventure:  Faced with corporate corruption in his civilian guise and petty crime as the Green Arrow, Oliver Queen begins to have an identity crisis, unsure of who he really is: Oliver Queen investor, or Green Arrow super-hero. Meanwhile, the Justice League of America is meeting in their secret headquarters with their new unofficial members, the Black Canary. They are recounting their recent adventure on Earth-Two against Aquarius and wonder if the battle against the magical living star had any ill effects on the group when suddenly the Black Canary unleashes a sonic blast that knocks all the other JLA members present for a loop.
