Smithsonian Miscellaneous Collections
Appears to be an original Spanish language version of the translation of volume 102 made by Charles Upson Clark in which the Smithsonian Institution received a fund in 1929 for research in European archives, in the hope of finding documents which would throw more light on the early American civilizations, especially that of the Mayas. Charles Upson Clark writes about his travel to Europe and his findings, including documentation by Vazquez de Espinosa.
