A stroll through Friedrichstrasse Bahnhof basement in 1990, where about 16 months previously the border controls for entry into East Berlin were situated. There was a row of cubicles with a solid counter inside, topped by a glass partition, behind which officers of the Border Police, their faces lit by creepy lights coming from below, checked your passport and issued a day visa. The reinforced doors opened and closed with solid metallic clunks. Once you got through those, there was a large area beyond occupied only by a desk in the middle where a single female officer issued you with the compulsory DDR currency at a 1 to 1 rate with the western Deutschmarks. The bottom picture shows what you saw when you finally got through the last door, the toilets, Damen and Herren, which you probably needed if you had been kept hanging around in the control areas for a long time.
