This document was selected for its testimony to the political commitment assumed by the artists of the Asociación Arte Concreto — Invención [Concrete Art and Invention Association]. The publishing project of the Asociación Arte Concreto — Invención consisted of two publications: the magazine Arte Concreto [Concrete Art], published in August 1946, and the Boletín de la Asociación de Arte Concreto Invención n°2 [Concrete Art and Invention Association Bulletin n° 2], which appeared in December 1946. The Arte Concreto magazine is also known as the Arte Concreto — Invención magazine, although its imprint specifies Arte Concreto. The writing committee was composed of Edgar Bayley, Simón Contreras, Alfredo Hlito, and Raúl Lozza. The Invention-ism Manifesto was published in this magazine and was accompanied by a Suplemento Poesía [Poetry Supplement] written by Contreras and Bayley. The Asociación de Arte Concreto — Invención was made up of Bayley, Antonio Caraduje, Contreras, Manuel Espinosa, Hlito, Enio Iommi, Obdulio Landi, Lozza, Tomás Maldonado, Alberto Molenberg, Primaldo Mónaco, Oscar Nuñez, Lidy Prati, Jorge Souza, and Matilde Werbin; Espinosa, Lozza, and Maldonado directed the secretariat of the organization. Juan Mele, Gregorio Vardanega, and Virgilio Villalba later joined the publications.
