Justice League of America #3

In "The Slave Ship of Space!", Kanjar Ro traps Earth in stasis, forcing the Justice League to aid him in a desperate battle across the stars. With only the voices of his enemies—Kromm, Hyathis, and Sayyar—able to break the freeze, the heroes face a chilling test of will and unity. Written by Gardner Fox and brought to life by Mike Sekowsky’s dynamic art, with Bernard Sachs’ inks and Gaspar Saladino’s crisp lettering, this 1961 classic features a cover by Murphy Anderson that captures the cosmic tension perfectly.
