The editorial efforts of the Asociación Arte Concreto — Invención [Concrete Art and Invention Association] yielded two publications: a magazine, Arte Concreto, published in August 1946, and the Boletín de la Asociación de Arte Concreto Invención nº 2 [Journal # 2 of the Concrete Art and Invention Association] that appeared in December 1946. The members of the Asociación Arte Concreto —Invención were Edgar Bayley, Antonio Caraduje, Simón Contreras, Manuel Espinosa, Alfredo Hlito, Enio Iommi, Obdulio Landi, Raúl Lozza, Tomás Maldonado, Alberto Molenberg, Primaldo Mónaco, Oscar Núñez, Lidy Prati, Jorge Souza, and Matilde Werbin; the administrators were: Manuel Espinosa, Raúl Lozza, and Tomás Maldonado. Later on, Juan Mele, Gregorio Vardanega, and Virgilio Villalba worked on the publications. Alfredo Hlito (1923-93) was as Argentine artist and a member of the Asociación Arte Concreto — Invención and the Grupo de Artistas Modernos de la Argentina [Modern Artists Group of Argentina]. He lived in Mexico City from 1963 to 1973, and died in Buenos Aires. This document has been chosen because it expresses the basic ideas of the artists who proposed an art they called invencionista [inventionist] which, as distinct from representation, sought to portray concrete reality.
