What is mail art?

Mail Art is a populist art movement centered on the creation and exchange of small-scale artworks through the postal service. It developed out of the Fluxus movement in the 1950s and 1960s and has since evolved into a global art movement. Ray Johnson is recognized as the first mail artist, and his New York School is considered the first network of mail artists. Mail artists rely heavily on a network to exchange their works, often creating a community of artists connected through the postal system.
