I assume you aren't reading the title. The way overlong story had the League split up to go to different time periods to retrieve some cosmic maguffins. So, we have Kamandi, JSA members from 1941, and the Justice League 1 Million members. I'm not particularly over-awed by the art and don't know why Rex Tyler Hourman is flying (over Captain Marvel's left). Although, there are still about a half dozen I don't know.
Yes, it's part of Lex's Year of the Villain though don't know where the Batman Who Laughs corrupting various heroes fits.
Apex Lex and Jokerized Bats duking it out for title of DC baddest now!
