But even before her own series debuted, she appeared with the Justice Society of America in All-Star #38, and with the next issue she began appearing on the cover:
At that point, she found herself without a feature as Flash Comics had been canceled by DC. By rights she should have disappeared like Starman and Dr Fate and many others had. Except... she got lucky. You see, she was not the only JSA member without a feature; longtime members the Flash and the Hawkman had their series canceled at that time as well, and Green Lantern was on his last legs. All-American had been converted to a western comic title the year before, and GL's own book mostly featured Streak the Wonder Dog on the cover for the last few issues. So she continued appearing in every issue of All-Star and occasionally popped up on the cover as well, until the JSA made its last appearance in #57.
Fast forward 12 years. In Flash #137, the JSA made its first appearance since that last issue of All-Star. Although the bulk of the story concerned Jay Garrick and Barry Allen teaming up against Vandal Savage, at the very end the two Flashes freed the old JSA members who'd been captured by that villain:
The GA Wonder Woman vanished and in her place was:
1. DC was still unwilling to acknowledge the notion of the GA and SA Wonder Woman being separate people, as it raised uncomfortable questions about whether the GA Superman and Batman were not the same characters we were reading in the 1960s. I note that the GA Superman and Batman did not appear for several years in these teamups (although oddly enough the GA Robin was prominently featured in the 1967 crossover).
2. There was little to differentiate the GA Wonder Woman and the Silver Age version (at the time). The GA and SA Green Lanterns had markedly different costumes, as did the two Flashes. The SA Hawkman hadn't entered the JLA as yet, so his similarity with the GA version didn't matter.
At any rate, Black Canary got lucky and was tapped for that very important team-up. And the next one:
The Starman/Black Canary pairing got a second outing the following issue (with a guest appearance by Wildcat). Those two issues are superbly entertaining, with terrific art by Murphy Anderson, but for whatever reason they did not result in a solo book for either character, and so it might appear that her luck had run out. Still, she got back into the JSA/JLA teamups with JLA #46-47, but then she got a bad break; in JLA #55 not only did the Earth-2 Robin appear, but so did that world's Wonder Woman. A big reason why the Black Canary had been featured in all those team-ups save one so far was that she was the only other female member of the JSA.
And then she got lucky again, and this time it was really a big break. In Wonder Woman #178 Diana Prince lost her super-powers and became an Emma Peel clone. A few months later, in JLA #69 WW left the Justice League to pursue her non-super career. This left the JLA as an all-male bastion, and in 1969, that was becoming an increasingly untenable situation. So a few issues later, when it comes time for the annual JLA/JSA teamup, a couple of things happen:
1. Larry Lance dies, heroically.
But all that is beyond the scope of this blog. Black Canary, you must be Irish!
