A vertical political poster features a large, centered illustration of an infant lying on its back, viewed from a low angle. The baby is wearing a dark grey gas mask that covers its entire face, with circular eye lenses and a ridged breathing tube extending from the snout down and towards the left, under the baby's right arm. The baby’s left arm is raised slightly, and its legs are bent and slightly off the ground, extending to the right off the poster's edge. The infant is printed in white and yellow, and the background behind the infant is black with wisps of grainy vapor undulating upward. At the top of the poster, the words "STOP WAR!" are printed in large, bold, orange capital letters, with "STOP" positioned slightly above and to the left of "WAR!". At the bottom of the poster, the word "VOTE" appears on the left under the infant in large, bold, off-white capital letters against the black background, and beneath that, "LABOUR" in even larger white lettering which spans the entire width of the image. The entire composition is framed by a thin off-white-colored border. There is a visible, vertical crease down the middle of the poster.
