The next exhibit in the Green Gallery at The Scrap Exchange features mail art sent to the Durham creative reuse arts center from around the world. Mail art (also known as postal art and correspondence art) is an art medium centered around sending small scale works through the postal service. Mail art can include a wide variety of collage, mixed media and other techniques. The artwork is usually sent without an envelope, so that postage stamps, cancellation marks, and wear and tear during the delivery process become part of the art as it passes from one hand to the next. The exhibit, titled “Signed, Sealed, Delivered”, opens on Friday, August 16 and runs through September 14.
