Frank R. Paul's Alien Spacecraft Encounter – Amazing Stories October 1927

Two white-coated scientists peer upward from inside a massive glass-and-steel geodesic observation dome as a bizarre mushroom-shaped alien vessel hovers in the star-flecked blue void above them. The alien craft — bulbous, red-capped, and bristling with antennae — glows with amber porthole light, suggesting both menace and wonder. Frank R. Paul's signature chromatic boldness turns this moment of first contact into a tableau of pure Golden Age awe: humanity small beneath the dome, the cosmos enormous beyond it.
