Atomic Age Sci-Fi B-Movie Poster (1950-1959)

Render this image as a 1950 to 1959 American atomic age science fiction B-movie poster, hand-painted in pulp gouache and oil on illustration board by a Reynold Brown or Joseph Smith school illustrator. Use a lurid pulp palette of radioactive green, warning sign red, electric arc cyan, ink black, atomic flash white, lunar gray, and one accent of laboratory amber. Compose with dramatic scale rupture between an oversized foreground threat and small panicking human figures, action-painted energy beams or rayguns crossing the canvas, and a deep space or laboratory background with halftone star fields. Render with confident pulp brushwork, glowing rim lighting on metallic surfaces, lurid colored cast light on faces, dramatic atmospheric perspective into the radioactive distance, and a heavy halftone print grain across the entire surface. The atmosphere is breathless, hyperbolic, paranoid, recruiting the Saturday matinee audience into a controlled rehearsal of nuclear dread. Strictly no on-canvas text, no title lettering, no legible type, no studio marks, no watermark. Preserve the subject, pose, and composition of the source image exactly, change only the medium and rendering. Aspect ratio matches source.
