Segundo de los libros-almanaques de Julio Cortazar, se publico por primera vez en Mexico en 1969 y fue disenado por Julio Silva. Cortazar se respondia a si mismo en una autoentrevista sobre el contenido: " en Último round hay un 'Homenaje a Alain Resnais' que se puede leer permutatoriamente, lo que modifica cada vez el sentido al mismo tiempo que conserva el clima inicial de 'L'annee derniere a Marienbad'. Hay tambien una despedida a Teodoro W. Adorno, que se ha convertido al catolicismo; hay varios cuentos, largos y cortos, hay una especie de diario de un dia de vida en mi aldea provenzal de Saignon. Hay una defensa de Salvador Dali (¡oh!); hay un examen general de los problemas del erotismo en la expresion literaria latinoamericana; hay un ensayo sobre el cuento breve y sus alrededores, cuestion que me sigue preocupando y sobre la cual no se ha escrito gran cosa. Te bastan esos botones, o necesitas todo el costurero?"
This second of Julio Cortazar's almanac-books was first published in Mexico in 1969 and designed by Julio Silva. In an interview with himself, Cortazar described the contents: "In Último round there is a 'Homage to Alain Resnais' which can be read in a permutational fashion, in such a way that its meaning changes even as the initial atmosphere of L'annee derniere a Marienbad is preserved. There is also a farewell to Theodor W. Adorno, who has converted to Catholicism; there are several stories, long and short; and there is a sort of diary of a day in my life in the Provençal village of Saignon. There is a defense of Salvador Dali (ah!); there is a general analysis of the problem of eroticism in Latin American literature; there is an essay on the short story and its surroundings, a subject which continues to preoccupy me and about which not much has been written. Are these samples enough, or do you want the whole sewing basket?"
