Wall cuts in the New York City subway

Wall cuts are panels in New York City subway stations where print advertising is displayed. Transit workers remove or paper over posters; "subway artists" tear layers to create collage-like effects and add graffiti; time passes and paper deteriorates. The results are a revolving display of found or accidental art, created on the fly and over time, through intentional acts and benign neglect. The panels are remarkable for their intrinsic beauty, variety and range of effect, and for being the product of random forces and human design.
