a result, she proposes to the engineer Marte R. Gómez, that the Mexican government supports the continuation of the construction works, with the condition that the muralist donate his collection to Mexico and turn the Anahuacalli into an archaeological museum. Nevertheless, this proposal was not carried out, at least not at the time. The first museographic design was prepared by Rivera himself under the direction of the anthropologist Alfonso Caso y Andrade (1896–1970). Both Caso and his collaborators recognized Diego's ability to distinguish, in his collection, the most authentic and important components. Despite the essential collaboration of Caso, Pellicer did not organize the exhibition following historical or anthropological criteria while working under the supervision of Rivera. Differently, Pellicer prioritized the artistic quality of the pieces to organize its display, since this had been Rivera's motivation to assemble the collection in the first place. For this reason, none of the objects are shown linked to a museum card, since Rivera's intention does not respond to an archaeological classification, but to an aesthetic admiration. When master Rivera died, the Anahuacalli was still in its process of construction; hence his daughter, Ruth Rivera (1927–1969) together with the architects Juan O'Gorman (1905–1982) and Heriberto Pagelson, finished this project with the financial support of Dolores Olmedo. Thus, the construction concluded in 1963 and the museum was inaugurated on September 18, 1964. In memory of its creator, the following quote was chosen for the inscription engraved on the museum foundation stone: "I return to the people what I was able to rescue from the artistic heritage of their ancestors. Diego Rivera". Anahuacalli's architecture Main building Due to the essential participation of Juan O'Gorman in the Anahuacalli's construction, it has been wrongly assumed that the building possesses an important functionalist influence. Nonetheless, by the 1940s, when the construction of the Anahuacalli began, O'Gorman had already stopped projecting in accordance with said architectural style. Distinctively, the Anahuacalli architecture was as a response to the growing presence of the International Style; O'Gorman realized that his early buildings, influenced by Le Corbusier, were not agreeing with the Mexican landscape and therefore considered them as "invasive species". As a result of the above, O'Gorman sought to return to a Mexican aesthetic for his designs, the one that is characteristic of popular Mexican folk art. The Anahuacalli responds to the ideal of a construction that is integrated with nature, typical of organic
