Vintage Sci-Fi Ray Gun Cover

A retro American comic panel in 1950s pulp sci-fi style of a brave astronaut named 'Rex Halloran' firing a glowing ray gun at a giant tentacled alien on a red-rock planet. Bold saturated colors, halftone dots, thick outlines, dramatic pose. A jagged burst reads 'ZAP!' beside the gun. A caption box declares 'Menace from Nebula Nine!' Faded newsprint texture, dynamic pulpy composition, campy heroic energy.
