Oh man. Even though this piece got boarded up last night, it didn't work. Someone still managed to get through and paint a beard and a red new medallion on the Priest in Banksy's Concrete Confessional.
The final result is definitely less powerful than before, and the beard seems to cover up some of the hidden face in this piece.
If there is a silver lining, it might be that whoever added the adjustments didn't cap the piece entirely.
