Operator #5, Volume 1, Issue 2, May 1934: #2 The Invisible Empire

Unseen, impregnable, the strange war engine of a foreign power hovered over America, waiting the fatal moment to hurl death upon a thousand cities and towns. Foredoomed to destruction and desolation before the ravaging hordes of the Yellow Empire, bleak despair gripped the nation’s millions. And then men held their breath in agonizing hope — as Operator 5, single-handed, seized the last grim chance to save the United States! Jimmy Christopher, clean-cut, square-jawed and clear-eyed, was the star of the most audacious pulp magazines ever conceived — Operator #5. Savage would-be conquerors, creepy cults, weird weather-controllers and famine-creating menaces to our mid-western breadbasket... these were but a few of the fiendish horrors that Jimmy Christopher was forced to confront.
