This work expands the term heterogeneity -used only in the peruvian case by the reviewer Cornejo Polar- and tries to define the kind of avant-garde that carried out in Valparaiso during de twenties, using the magazines Litoral (1927-28) and Nguillatun (1924). The aim of this work is to particularize Chile as an isolated case of heterogeneity; a case in which double sociocultural status will emerge in the gap, not between indigenism and indigenist, but between tradition and modernity, highbrow and lowbrow or, extensivily, between urbanity and rurality.
