Mail art is also often called correspondence art. Mail art is, basically, art sent through the mail, including faux postage, postcards, ATC's (Artist Trading Cards), copy art, handmade books, etc. Not all mail art is rubber stamped, though rubber stamps are used on mail art quite often and there is a strong overlap among stamp artists and mail artists. Much mail art is dadaesque, but another common school of mail art is a lush, collaged style similar to the work of Nick Bantock in the Griffin & Sabine books. An artistamp is something on a piece of paper or card that looks suspiciously like a stamp of some form. It is usually attached to another piece of paper or card and many regard it as much more attractive and interesting than the "real" postage stamps. Also called Faux Postage.
