Lisbon Graffiti

Lisbon is the beautiful, sun-soaked capital of Portugal.  The crowded streets are flanked with buildings of every shade of pastel-color imaginable.  What really caught my eye here, however, was the abundance of graffiti on every wall.  This series explores the contradiction between the traditional beauty of the buildings and the spray-painted alterations that cover them.  Do the designs add to the experience? Or do they degrade what is already beautiful?
