A large, horizontal billboard is centered in the image, displaying an advertisement. The billboard features a white background with two illustrations of human heads contained within transparent glass jars with screw-top lids. The head on the left, a male with dark hair, has an exaggerated expression with eyes rolled upwards and the tongue partially extended. The head on the right, a male with lighter hair and a beard, also has eyes rolled upwards and a slightly open mouth. Between these two images, text is displayed: "SINCE 1979" at the top, followed by "Communication design that lasts!" in a larger font, and "Design para comunicação, que dura!" in a smaller font below. In the foreground, the upper portions of multiple vehicles are visible, including a white van on the far left, a dark grey SUV centrally, and a dark vehicle with a red taillight on the right. The background consists of numerous tall, dark green conifer trees silhouetted against a light, hazy sky. The scene is located in the city of Almancil, Portugal.
