The image shows a two-lane highway with a white warning sign from the Allied forces posted at its edge. The English inscription cautions travelers: ‘FOR THE NEXT 2 MILES YOU WILL BE IN THE SOVIET ZONE – DO NOT STOP.’ A heavy tanker truck passes the sign heading toward Berlin; on both sides, Brandenburg pine forest lines the route. The photograph was taken in 1955 on the transit corridor between West Germany and West Berlin, likely near Checkpoint Dreilinden. The sign illustrates the everyday reality of the Cold War: every connection between West Berlin and the Federal Republic had to pass through Soviet-controlled territory, and Allied authorities cautioned their personnel to proceed carefully and without stopping. The image exemplifies the geopolitical isolation of West Berlin as an enclave within the Soviet occupation zone.
