"Mail art becomes art when anyone who sends or receive it in the mail decides to call it art." -Thomas Cassidy "Mail-Art , It's been said that mail art was created in the 60's from Fluxus, and Dada ,was begun by artists who did not believe art should be limited to the gallery and museum walls. It has the aim to create possibilities for direct exchange of art, ideas and information between artists in different countries, without going through the established art markets. The person credited with being the father of mail art as we know it was the late Ray Johnson ."
Mail-Artists have always experimented with different art forms; collages, stamps, post cards,stickers,faux postage stamps,also known as artistamps, "objects d'art", audio, video etc. .
