Cosmic Treadmill, Episode 50
Crisis on Infinite Earths, Part 1

For the landmark 50th episode of Cosmic Treadmill, Chris (@AceComics) and Reggie (@reggiereggie) celebrate with the 50th anniversary celebration of DC Comics, and read issue #2 of Crisis on Infinite Earths by Marv Wolfman and George PĂ©rez! After some creator bios and an exhaustive look at the conditions that created the DC Multiverse, our intrepid comics enthusiasts sift through every appearance of a central figure to Crisis--before the event ever happened! After a break, our Treadmillers summarize issue #1 and detail issue #2 of Crisis on Infinite Earths! And that's all we have time for this week--tune in next Sunday for part two of this series!
