In Belgrade, Serbia, at night, a large white rectangular advertising billboard is being installed or dismantled. The billboard is angled and illuminated, displaying a textured white surface. A white utility van, equipped with orange flashing hazard lights, is parked in front of the billboard on a city street, likely at a pedestrian crossing. A ladder is propped against the billboard structure, and at least two individuals are visible near the ladder and the billboard, appearing to be working on it. One person, wearing a light-colored shirt, is positioned higher up on the ladder. Another person in dark pants and a lighter top is also visible. A traffic light with a red signal is illuminated on a pole to the left of the billboard. The street appears wet, reflecting the lights. Trees and buildings form the background, partially obscured by darkness.
