I have a lot of smart readers, so I'm going to throw out a comics-related question that I truly don't know the answer to. If you know the answer, or know where to find it, please let me know!
Here's the set-up and then the question. In the final issue of "The Great Darkness Saga," originally published in The Legion of Super-Heroes #294 (December 1982), Paul Levitz includes over 50 (I count 51, but I'm sure I'm missing a few) different characters from the DC Universe (not including all of the unnamed characters in the issue, like the Daxamite army and the floating dead bodies around the galaxy). A few years later (1985) Crisis on Infinite Earths #1 surely had more characters than that. So my question is Was Levitz the previous record holder for most characters in a single issue?
Did any comic book have more than 51 significant characters in any issue before December 1982? If so, what issue of what comic? How many characters appeared?
I want to know these things.
