Art is anywhere, anytime; it just depends on your viewpoint. Not every artist can afford a canvas to create on; some people's imagination exceeds their financial or physical means. Sometimes the canvas is bigger than ourselves. Look at Banksy or Michelangelo. Subway cars in the 1970s and 1980s became mobile murals in New York City. Sometimes the canvas is really small. And free. And courtesy of the U.S. Postal Service. Label 228 is a gathering of street art executed on priority mail labels (label 228, in U.S.P.S. parlance) and displayed in public spaces. It's a remarkably popular method of exposure featured by graffiti artists worldwide. These labels are free, portable, and quick and easy to exhibit, offering artists the chance to spend more time creating their work than if they were to paint and write directly on walls, vehicles, or public objects. Camden Noir launched his Label 228 project by putting out a call to artists, asking them to send him their artwork or anything, for that matter, on priority mail labels. Within six months, he received more than 500 labels from artists all over the world. At this point, he has more than 1,500 labels from more than 600 artists. This is a collection of the best of those labels, in a beautiful, full-color book.
