The purpose of this article is to analyze the architectural and curatorial discourse of the Mexico"s pavillion at the 1970 Osaka World"s Fair. The relationship between the discourse of the building itself, designed by Agustin Hernandez, and the murals commissioned by Fernando Gamboa allows us to examine the sense of national identity promoted by the cultural policies of the Mexican government. These policies aimed to emphasize the country"s cultural heritage and artistic innovation within the international context of world"s fairs.
