Frank R. Paul's Lunar Concession – Science Fiction Magazine Sept 1941

Predicting lunar colonization with surprising accuracy but dressing it in tropical jungle flora, this 1941 cover imagines the Moon as a lush battleground rather than the barren gray wasteland Apollo astronauts actually found. A heroic spaceman in a green tunic shields a blonde woman while an explosion erupts behind them, a sleek rocket ship hovers in the crimson sky over jagged alien rock formations, and a menacing red-suited figure lurks in the background — pure space opera gold.
