Right around this point the JLA got their own issue of DC's odd but fun in-house fanzine, The Amazing World of DC Comics. The cover is a rarity, in that it features Dick Dillin's pencils reproduced directly.
Almost the entire issue is devoted to JLA history, starting with a brief rundown the book to this point, and followed by "The Men Behind the JLA" focusing on the men who have written the team's adventures:
Next is an issue-by-issue summary of every JLA issue, including reprint collections and the initial tryout in Brave and the Bold.
Next are the JLA's by-laws(!), where we see the official list of Honorary Members: Snapper Carr, Adam Strange, Batgirl, Martian Manhunter, Vigilante, Sargon, Phantom Stranger, Black Lantern(*cringe*),and Charley Parker.
We also have this section of the by-laws, which would become very significant later on:
(There was a very funny column by Bob Ingersoll about how, according to this by-law, Aquaman had absolutely no right to do what he did in disbanding the JLA all by himself in JLA Annual #2. While Bob is right of course, these by-laws were printed in 1977 and could've been changed between then and 1984, the Annual's publication date. Oh, and I love that all the JLA's stuff reverts back to the Wayne Foundation!)
Along with that, we have schematics of the JLA HQs:
...I like that one room, in the far left circular chamber, is called "Think Tank." Why do I think only Batman thinks he should be allowed in there?
Next are profiles of the individual members, guest-stars, and even some of the villains, followed by an interview with JLA editor Julius Schwartz.
The inside cover features a JLA cover gallery, and then the back cover features a real rarity, a rejected original cover for JLA #66 by Dick Dillin, a cover later re-done by Neal Adams:
...I can see why this got rejected. It's nicely drawn and all, but you rarely see superhero comics where its the villains that look like they're the ones outmatched.
I generally enjoy all the issue of AWODCC, because they're such a grab-bag of odd features. Nice to see the JLA get an issue all to itself!
