All-Star Squadron #15 November, 1982.

On Earth-Two in January 1942, in Per Degaton's control room, he gets the news that the Justice Society has come after him, from forty years in the future. It doesn't faze him at all. On a huge video monitor, Degaton and at least five henchtroopers are observing a U.S. battleship steaming in the North Atlantic, via aerial TV camera. On the main deck are fifteen colorful figures from three super teams: Aquaman, Commander Steel, Doctor Fate, Firebrand, Firestorm, Green Lantern, Hawkman, the Huntress, Johnny Quick, Liberty Belle, Power Girl, Robotman, Starman, Superman, and Zatanna. Degaton's sensors reveal that five of them are from a future decade of a parallel world, which still doesn't bother him. But he's able to eavesdrop on them, and the heroes don't seem to know they're being observed, so Degaton's mad overconfidence may not be completely unwarranted.
