During my ongoing survey of the legendary JLA & JSA team-ups, I've come across some pretty spectacular fight scenes.
With all of that multiple-earth mayhem to chose from, the scene that just seemed right for the All-American Labor Day Weekend featured the personification of America itself: Uncle Sam!
Taken from Justice League of America #108 (1973), the JLA & JSA are helping Uncle Sam and his Freedom Fighters liberate Earth-X from Nazi rule. Breaking into smaller squads, the heroes track down and destroy Nazi mind-control machines hidden in various locations across the planet. In this chapter, Uncle Sam, Black Condor, Sandman and the Elongated Man arrive at a twisted version of Mount Rushmore, which includes a bust of the hated Adolph Hitler!
After a quick assist from E.M., it's Uncle Sam with the windup... AND THE PITCH!...completely obliterating the granite visage of Herr Schickelgruber and the hidden mind-control device.
GOD BLESS AMERICA...AND BAHLACTUS!
