A vertical propaganda poster features a central illustration of a giant, red hand holding a gray wrench, emerging from the top left and thrusting the wrench downwards between two large, black industrial gears. The hand is positioned against a light blue and white background, and the lower end of the wrench are wedged in the gear teeth, causing one to crack. Radiating lines from the wrench and gears emphasize the violent movement of the action. At the hub of each gear is a black and gray swastika. The top of the poster contains the bolded text "COMBATTANTS ALLIES" in a thin light blue bar, followed by the larger, bold text: "Vos compatriotes en pays occupé frappent aussi!" The color palette is dominated by red, black, gray, and light blue, utilizing sharp, geometric lines characteristic of mid-20th-century graphic design.
