According to Wikipedia, the stencil circulators use paper, cardboard, or other media to create an image or text that is easily reproducible (wikipedia). The desired design is cut out of the selected medium and then the image is transferred to a surface through the use of spray paint or roll-on paint.
Freedom Of Opinion
Some of the stencils contain political messages, others distribute advertisement, artistic impressions, provocations or just the fun to publicize something. They show the freedom of opinion.
I enjoy discovering those stencils on my ways through Manhattan. You can find them on walls, doors, lamp posts, mail boxes, energy transformers and where else. They may be art or not, I don´t care.
The tiny publications make New York City more colorful and cool. Some inspire me to think about. Others are just fun.
Often you can find clusters of different stencils that form a pattern - accidental or not. Those collages are an art form by themselves.
