Wistful Beauty or Berlin's Mona Lisa

Today I took the U2 to Nollendorf Platz.
Then walked along underneath the viaduct , direction Gleisdreieck.. The wall art was plentiful and amazing. Possibly a trip every other day will suit me and enable me to capture  some amazing work. This piece impressed me as it has a 3D effect and great beauty. The extra , taken from a different angle seems to present another expression. Berlin's Mona Lisa ?
