A massive catalogue of the most representative of the 20th century art produced in Latin America based upon the collection of its founder, Eduardo F. Costantini. The edition comprises 140 pieces, including paintings, drawings, sculptures, objects and installations by 96 prominent Latin American artists, such as Tarsila do Amaral, Diego Rivera, David Alfaro Siqueiros, Frida Kahlo, Antonio Berni, Lygia Clark, Alicia Penalba, Wifredo Lam, Emilio Pettoruti, Xul Solar, Gego, Julio Le Parc, Roberto Matta, Helio Oiticica, Candido Portinari, Antonio Berni and Jorge de la Vega, among many others. This catalog includes for the first time a selection of the bibliographic records resulting from the Proyecto de Investigación de la Colección (Research Project of the Collection), initiated and directed by Agustín Pérez Rubio in 2015 (Artistic Director of the museum 2014-2018 ), so far only accessible on the museum's website. The project involved more than 70 international researchers and specialists, who wrote texts about each of the works. This allowed to review and expand the knowledge about the Malba Collection and to make this exhaustive file available to the public. The book also includes texts by art collectors Eduardo F. Costantini and Ricardo Esteves, and an essay by Victoria Giraudo, Chief Curator of the Museum.
