The exhibition that took place in the Palacio de Bellas Artes [Palace of Fine Arts] revolved around four exhibition-tributes dedicated to José Clemente Orozco (1883–1949), Diego Rivera (1886–1957), David Alfaro Siqueiros (1896–1974), and Brazilian artist Candido Portinari (1903–1962). Gerardo Murillo (Dr. Atl), Juan O’Gorman, Jorge González Camarena, Francisco Goitia, Carlos Orozco Romero, Jesús Guerrero Galván, Guillermo Meza, Juan Soriano, Cordelia Urueta, Ricardo Martínez, Olga Costa, and many others participated in the Mexican competition. The foreign artists who participated in the biennial included Jack Levine, Stuart Davis, Joseph Albers, Mark Tobey, and Morris Graves, and the Abstract Expressionists Sam Francis, Philip Guston, Willem de Kooning, Franz Kline, Adolf Gottlieb, Theodore Stamos, and Kenzo Okada.The international jury’s panel was led by Miguel Salas Anzures as president, and its members were Amelia Peláez of Cuba, Hemult Hungerland of the United States, Luis Cardoza y Aragón of Guatemala, and, from Mexico, Justino Fernández, Jorge Juan Crespo de la Serna, David Alfaro Siqueiros, Leopoldo Méndez, and Antonio Rodríguez Luna. Though the exhibition included some examples of semi-figuration and abstraction, the awards clearly indicated that officialdom continued to support the turn-of-the-century realist trend. This turn of events provoked a considerable amount of reproaches and criticism; as in previous years, Rufino Tamayo (1899–1991) was not the only person in disagreement, so that his bickering was echoed by the critic Alvar Carrillo Gil; the painters Alberto Gironella, José Luis Cuevas, and Juan Soriano; and many others. By and large the biennial was poorly represented: many artists were not included, and the works that the participating artists sent for exhibit were not the best of their respective œuvres. Regarding the awards granted, it was mentioned that neither Goitia nor Dr. Atl should have entered the competition at all. Though non-objective or abstract painting was present, people certainly felt the absence of many painters that were part of this trend such as Venezuelan Alejandro Otero and Columbians Barrios Salvatierra and Alejandro Obregón. At the time there was confusion regarding the meaning of abstract art. Many painters and art critics believed that it was merely a pointless and dehumanizing proposition.
