Teen Titans #20

In "Titans Fit the Battle of Jericho," Neal Adams and Sal Amendola deliver a gripping tale as the young hero Joshua infiltrates Teen Titans headquarters, desperate to enlist their help in halting a dangerous scheme. With the fate of Earth hanging in the balance, the Titans must confront a mysterious alien plot orchestrated through unwitting teenage allies—before it's too late. The cover by Nick Cardy captures the urgency of the moment, a 12-cent comic from 1969 that remains a standout in the early Teen Titans run.
