Red Line

This was taken in Berlin when I was there a few weeks ago together with my boyfriend. When I am there I am always on the look out for street art, and when we were about to visit East Side Gallery and got off at the closest station, we spotted this beauty in the background. I have seen 'his' work in books and such but never with my own eyes, so I was very excited to have found it. I'm not sure why I like this picture so much, I guess it is the blue sky in combination with the bright red of the train.
