In Sofia, Bulgaria, under a cloudy sky, a large, olive-drab anti-aircraft gun is displayed outdoors on a concrete base. The gun has a long barrel pointing upwards and to the left, with a distinctive muzzle brake. It is mounted on a wheeled carriage with large tires. Behind the gun, a white building with an orange tiled roof and multiple windows is visible. To the left of the gun, a white police van with blue and yellow markings, including the word "POLICE," is parked. A tall, leafy green tree occupies the right side of the frame, partially obscuring the background. In the distance, other buildings and a fire truck can be seen. A group of people, some in casual attire and others possibly in uniform, are standing near the back of the scene. A blue flag with white lettering is also present. The ground in front of the display is covered in grass.
