At this time, the wall was still in function and the city was still devided.
I took this picture 7 1/2 weeks before the fall of the berlin wall, with my old analogue SLR (Praktica MTL50). It's shot from the western side, where you could walk straight besides the wall and sprayer could do there work.
Behind the wall, you see the Brandenburg Gate, the tv-tower and other buildings of former East-Berlin.
