This publication documents the 1958 Guggenheim International Award, the second installment of a prize established in 1956 "to stimulate interest in contemporary art and in this way encourage the work of artists throughout the world." An international jury awarded $10,000 to a chosen artist; additional awards were conferred to artists by nationality. The winner of the 1958 International Award was Spanish artist Joan Miró, for Day and Night, a ceramic mural designed for the UNESCO building in Paris. The catalogue includes a color foldout reproduction of the mural's component Night and a checklist of participating artists.

The International  Award, National  and Extra-National Prizes are outright grants. The aim of the Award is to stimulate public interest in contemporary art  and in this way to encourage the work of artists throughout the world.
