This might be seen by many cities as a representation of vandalism that has to be quickly erased from public viewing, but other cities like New York might take this as urban art and even a tourist attraction for an art lover. They are in the most unexpected locations you could imagine, the rooftop of a building, down the alley, or just by the fire hydrant. Many of the art pieces will stay permanently there until another artist comes in and makes another great piece of art or time and the weather starts taking it down slowly.
During my recent trip to New York City, I took a walk on the High Line in the Chelsea neighborhood to see the re-proposed, old train track turned into a city green space. It was the perfect day to walk, and to my surprise check out original art.
