Oftentimes, I find the creation of art more interesting than the final result. To this extent, I've always been interested in the washes of color used to cover up graffiti.
These blank pieces of paint generally do more to draw my eye to a wall or fence than the original graffiti.
This out of place look, coupled with the deterministic and accidental design implemented by the individual covering the graffiti, lead me to wonder what is under the graffiti? Additionally, since the paint-over is generally white, what piece of graffiti and subsequent cover up will follow?
