Vintage Propaganda Poster with Frog

A vintage-style propaganda poster with a sepia-toned color scheme. In the foreground, a large frog-like creature with a spotted green body and blue belt stands in profile facing military personnel in dark uniforms and gas masks. The military figures are rendered in silhouette, creating a stark contrast against the lighter background. The text "RESIST" appears in large, bold, yellow letters at the bottom of the poster. The image has a weathered, textured appearance with aging effects and vignetting around the edges. The overall composition creates a dramatic juxtaposition between the natural and military elements, with the creature positioned as a direct challenge to the armed forces. The poster has a dark, ominous atmosphere enhanced by the monochromatic color palette and shadowy details.
