This paper aims to analyze the dialogues between the works of Oswald de Andrade, Blaise Cendrars, and Tasila do Amaral, based on the notion of “telegraphic language”, which is the despoliation of artistic expression, a characteristic of modernity. While technical advances heralded new forms of communication, such as telegraphy, the avant-garde adhered to this spirit of innovation, initiating the synthesis and simplicity of artistic languages as a novel means of expression. For the analysis, we will consider the works Feuilles de Route, Pau Brasil, and Tarsila’s sketches for both books. For theoretical purposes, studies of avant-garde and modernist aesthetics will be considered.
