Like Celia Calderón de la Barca’s Ballad of Diego Rivera on the other freestanding wall, this work by Alberto Beltrán features a corrido, a type of narrative song often about oppression that was popular in twentieth-century Mexico, Nicaragua, and other Latin American countries. Based on the emergence of the Communist-leaning World Peace Council in 1949, this poster pairs Beltrán’s imagery with prose by Cándido Tepepa (pseudonym of Luis Córdova), recounting an international meeting of birds who try to stomp out the U.S. contingent. In the song, Tepepa denounces American emissaries as “bloodsuckers,” citing their “atomic excrement” as proof of their destructive nature.
