Unión de Escritores y Artistas de Cuba / UNEAC (cover designers: Raúl Martínez and Darío Mora, chief editor: Otto Fernández), "Unión: Revista de la Unión de Escritores y Artistas de Cuba, No. 3, Año VI," September 1969. Offset print, magazine.

The cover of "Unión" No. 3 showcases Raúl Martínez and Darío Mora's striking geometric design featuring interlocking three-dimensional letterforms rendered in vibrant blue diagonal stripes with magenta accents against a cream background. The bold, architectural composition creates an optical illusion of depth through careful use of parallel line work and angular shapes. The outlined "UNION" logotype at the top, combined with the dense listing of international contributors (Weiss, Landolfi, Enzensberger, Nathaniel Tarn, Reinhard Lettau, Aparicio, Triana, Rodriguez Feo, Pita Rodriguez, Reynaldo González), signals the magazine's cosmopolitan literary ambitions. This modernist cover design reflects UNEAC's role in positioning Cuban revolutionary culture within international avant-garde circles during the late 1960s.

Published quarterly by the Unión de Escritores y Artistas de Cuba, "Unión" served as one of the most important literary journals of post-revolutionary Cuba. This September 1969 issue opens with Nicolás Guillén's seminal essay "Acrecentar la obra propia en mensaje artístico, revolucionario y popular" (Enhance One's Own Work with an Artistic, Revolutionary, and Popular Message), delivered at the UNEAC awards ceremony for the prestigious David Prize competition. Guillén's address contextualizes Latin American independence struggles from Bolívar through Martí, arguing for the indestructibility of creative intelligence even during political crisis and emphasizing that the war of independence continues in new forms against North American imperialism.

The issue features an impressive roster of international and Cuban contributors including Peter Weiss, José Rodríguez Feo's notes on reading Poe, Miguel Collazo's story "El sapo," illustrations by Eugenio Rodríguez, Tommaso Landolfi, José Triana, Raúl Rivero, Helio Orovio, Raúl Aparicio, Hans Magnus Enzensberger, Alexander Kluge, and poetry by Manuel Díaz Martínez and Reynaldo González. The distinguished editorial board included Angel Augier, Miguel Barnet, Alejo Carpentier, Eliseo Diego, Gustavo Eguren, Pablo Armando Fernández, Nicolás Guillén, César Leante, José Lezama Lima, Enrique Oltuski, Heberto Padilla, Félix Pita Rodríguez, and José Antonio Portuondo. Printed by the Instituto del Libro at Unidad productora 01 "Osvaldo Sánchez," this issue exemplifies UNEAC's mission to foster revolutionary artistic creation while maintaining international literary connections during a pivotal moment in Cuban cultural history.
