The idea comes from observing the saturation of public space with advertisements. In many cities, public transport vehicles are also covered with advertisements. Since public transport vehicles are public property, the same logic can be applied to police, ambulance and fire trucks, which are also publicly owned.

The work was never carried out, but the sketches serve as a hint to decision-makers about the potential of the still unsaturated public surfaces. A premium package could include strobe lights to ensure visibility.

The sketches are based on photographs of Ljubljana city buses.
