The JLA versus Sorcery, in another 80...er, 64-Page Giant.
The stories: "The Fantastic Fingers of Felix Faust!" (JLA #10), and "One Hour to Doomsday!"(JLA #11) by Gardner Fox, Mike Sekowsky, and Bernard Sachs.
Roll Call: Superman, Batman, Wonder Woman, Aquaman, Flash, Green Lantern, Martian Manhunter, Green Arrow
Notable Moments: Cover by Curt Swan (who you didn't see draw the JLA much) and Murphy Anderson--I especially think the cobwebs are a nice touch.
DC had a couple extra pages, so this book also features a Knights of the Galaxy story, "Lives of a Rocket Lancer!" by Robert Kanigher, Carmine Infantino, and Bernard Sachs, from Mystery in Space #8.
If you look at the ad for the book below, either the cover was originally going to have a black background or it's just a mistake. I think I like the black better...
