Mexican artist Ulises Carrión was  a pioneering figure in mail art, a movement and a medium that pro­duced a unique international network of creative exchange in the 1970s and 1980s. Throughout his life, he developed an important oeuvre that spanned performance, video art, and books. Published in conjunction with the exhibition Ulises Carrión: The Big Monster, this illustrated booklet features essays by Aimé Iglesias Lukin and Zanna Gilbert on the genesis and main projects of Carrión’s visionary work.
