[Mexico City]: Taller de Grafica Popular, . First Edition. Quite rare post-war corrido broadside celebrating the American Continental Congress for Peace, held in Mexico City in September, 1949. The Peace Congress was singled out by the House Un-American Activities Committee in a 1951 report as a Communist-fronted event, "...aimed at consolidating anti-American forces throughout the Western Hemisphere." American attendees to the Congress included Linus Pauling, W.E.B. Du Bois, Paul Robeson, Ben Shahn, and Charlie Chaplin. The ballad composition is credited in type to one Cándido Tepepa, "vive por Chinameca"; but Prignitz attributes the text to the Veracruzano poet Luis Córdova (without mentioning the presence of the "Tepepa" credit in the text). The only institutionally-catalogued copy in OCLC (UCSD) gives Tepepa as a pseudonym, citing Prignitz, but we would say Prignitz is unclear on this point. Broadside, 47cm x 35cm. Printed recto-only, on newsprint. Text in 4 columns beneath woodcut illustration, within decorative border; 8 cuts in text. Illustration signed "beltrán" in type, below image. Old folds; edge-chips; paper moderately browned; about Very Good.
