Panels from Justice League of America (1960 series) #107 (September-October 1973), script by Len Wein, pencils by Dick Dillin, inks by Dick Giordano, colors by Glynis Wein, letters by Ben Oda
All is darkest before the dawn (and also because my scans didn't turn out as bright as I'd hoped on those last panels), but luckily the JSA is accompanied by their Earth-1 non-union equivalents, the Justice League of America! Er, at least, Green Arrow, Elongated Man, and...Red Tornado, not even actually yet a member of the League. Oh man. They're boned.
Hooray! It's the Nazi-bustin' heroes of Earth-X! The Earth where no one under the age of eighteen will be admitted, cos' it's kinda saucy. It's...Amerihat! Gnat Boy! Cling-Film Woman! Captain Rhinoceros! Designed-By-Mike-Grell-Costume Kid! And Poppin-Fresh! They are the Freedom Fighters!
I kid the Freedom Fighters, but they punch Nazis, so they're okay by me. You go, FF!
