Two policemen wearing white helmets stand on the ground, one holding the ladder, the other to the right holding the coiled length of electrical cord attached to the microphone. The van has "CD service" written on the side. There are 2 loudspeakers attached to the metal armature on top of the van that are also supported on metal poles; one speaker behind the man to the left and one to the right.
