retro poster design — Bottom Title · Split Layout · Two Figures

A vintage war movie poster split between a bright yellow upper half and a naval battle scene at the bottom. The background of the upper half is a flat, saturated golden yellow filling the frame from the top edge to mid-frame. In the upper center, two large painted heads of adult men float against the yellow: on the left, an older adult man with graying hair, a lined face, and a dark naval uniform collar, mouth open mid-shout; on the right and slightly larger, an adult man with short dark hair and a stern, anxious expression, wearing an open-collared shirt. The heads are rendered in a screenprint style of black and olive-yellow tones. In the lower half, a black submarine surges through dark blue-green ocean waves, white foam breaking around its hull. Behind it on the left, a warship burns with jagged red and yellow explosion bursts. On the right, another naval vessel erupts with tall red fire plumes while small silhouetted aircraft cross the sky. Across the bottom of the frame, a white horizontal box carries the "TITLE" in bold red italic capitals with a thin black outline. In the upper-left corner, the yellow field is interrupted only by a small dark speck. In the lower-left corner, dark waves crash white against the submarine's bow. In the lower-right corner, red explosion tongues rise beside a smoking smokestack. The lighting is flat and posterized, with no cast shadows in the yellow field, while the battle scene below uses high-contrast glints on the wave crests and glowing red fire light against the dark water. Overall, the twin faces floating above the diagonal clash of black ships and red fire pairs a stark yellow-and-black palette with bursts of red and ocean blue in a bold 1950s painted poster style, creating an urgent, explosive mood of underwater warfare.
