Today I am dreaming about my next trip to New York. When that day comes, there are sure to be visits to more than one museum. The entire city is my museum. Let me wander up and down a few of the less glamorous streets and I will happily spend an hour studying brickwork, stone cherubs and fire escapes. Neglected doors are canvases for those with no gallery representation. They are group efforts, tagged, stenciled, stickered and scraped. Artists work for years to develop a similar multi-layered look. In a city, it happens organically.
