Unión de Escritores y Artistas de Cuba (cover designer: René Ascuy, design: Héctor Villaverde, director: Otto Fernández, illustrator: Luis Martínez Pedro), "UNIÓN: Letras de Mongolia," late 1970s.

UNIÓN, the official magazine of the Unión de Escritores y Artistas de Cuba (UNEAC), served as the premier literary and cultural journal of revolutionary Cuba, providing a platform for both Cuban and international writers. This special "Letras de Mongolia" issue represents Cuba's cultural exchange programs with socialist nations, particularly highlighting literary connections with Mongolia during the 1970s.

The cover design by René Ascuy employs striking photographic halftone imagery of walking legs over scattered flowers, creating a contemplative composition that speaks to themes of journey and natural beauty. The bold red typography listing featured Mongolian and Cuban writers—including Nicolás Guillén, Alexandr Blok, Angel Augier, Félix Pita Rodríguez, Fina García Marruz, Miroslav Válek, and Eliseo Diego—establishes the international scope of this literary exchange. The large "UNIÓN" masthead anchors the design with its characteristic bold lettering.

Interior illustrations by Luis Martínez Pedro, including a powerful woodcut-style eye motif, complement the Mongolian poetry and prose translations. The magazine's design by Héctor Villaverde maintains UNIÓN's clean, modernist aesthetic while accommodating the special thematic content. Under director Otto Fernández, this issue featured translations of contemporary Mongolian poets alongside critical essays examining Tolstoy's influence on Cuban literature and poetry by established Cuban voices.

Published quarterly from the UNEAC offices at Calle 17 y H in Vedado, Havana, UNIÓN magazines like this were printed at the Empresa "Ediciones Cubanas" and distributed both domestically and internationally, representing Cuba's commitment to socialist cultural solidarity and literary exchange during the revolutionary period.
