When it was inaugurated in 1964, as part of the program of institutionalization of culture that characterized the government of Adolfo López Mateos, the Museum of Modern Art acquired the status of official emblem of the modernization of the country. In those years, the National Museum of Anthropology, the Anahuacalli Museum, the Pinacoteca Virreinal (building that now houses the Alameda Art Laboratory), the Museum of Natural History and the Museum of Mexico City were also opened. Despite the fact that, at first, the MAM rooms adopted a broad historicist profile, they soon relied on renovation and, therefore, on an updated image of national art that questioned the discourse of national identity inherited from the Revolution, through the first great exhibition dedicated to Rufino Tamayo, who at the time embodied the revocation of the muralism codes and the Mexican School, the unprejudiced openness to the criteria in vogue worldwide.
