This is the famous crossing Unter den Linden – Friedrichstraße in the middle of Berlin, near Brandenburg Gate. You see a lot of people in the Friedrichstraße, one of the most famous shopping streets in Europe, even today. Also horse-drawn carriages and a wonderful red car. Does anyone know the car-type? Maybe a Mercedes?
(Unfortunately the stamp is already missing.)
