Thirteen Against the Earth!, script by Len Wein, pencils by Dick Dillin, inks by Dick Giordano; cCover art by Nick Cardy. The Justice League, the Justice Society (Earth-2) and the Freedom Fighters (from an Earth where the Nazis won WW2) split up to tackle the machines controlling the Earth, with each machine more difficult to destroy than the last; When the three groups confront the final machine inside of an orbiting satellite, the machine reveals its origins of how the Nazis created it to help run things, but it eventually turned on its creators and Adolf Hitler himself seeing them as inferior per its programming; The last machine is destroyed by Red Tornado's sacrifice yet again, and the three groups, triumphant, return to their respective earths along with the surviving Red Tornado, who chooses to stay on Earth-1

Good condition.
