This is a mural created by the italian street artist BLU. You find this one in Berlin-Kreuzberg, near Oberbaumbrücke, it is located at Schlesische Straße / Cuvrystraße. The motive refers to the historic background of this place, which is very near to the former inner-german boarder. One character forms an E and the other one a W – which means east and west! Nearby you can also find the famos pink man by BLU.
