Mail art is a form of artmaking that relies on the postal system to circulate objects and ideas. Artist-made postcards, collages, disassembled sculptures, audiovisual works, artists’ books, xerox art, rubber stamps, artists’ postal stamps, magazines, and more conventional letters, all traveled through the mail art network. Though well-known artists participated, mail art was largely an alternative art form that allowed lesser known artists to circulate their work outside of the mainstream gallery and museum system. A collaborative ethos underpinned mail art, as artists embraced the possibility of exchanging objects and ideas with peers around the globe. In the 1970s, Carrión served as a key participant in this network, facilitating cross-cultural connections and theorizing the relationship between art, mail, and political power.
