"Where on Earth am I"
Two comic-book creators from Earth-Prime find themselves transported to Earth-1 and Earth-2, via the Flash's Cosmic Treadmill. The trouble begins as the now villianous Cary Bates, tricks the Justice League into "Killing" members of the Justice Society.
(Note: This book features Robin, Wonder Woman, Shade (villain) and the Huntress (villain) from Earth-2. Also E. Maggin addresses Hawkman as Carter Hall in this book.)
