A shocking report from a researcher in Mexico City found that most of the San Francisco-based Mexican Museum‘s permanent collection of artifacts are either forgeries or cannot be authenticated. The grim findings came in a 14-page report commissioned by the museum’s board and were submitted late last month by Eduardo Pérez de Heredia Puente, an associate at the National Institute of Anthropology and History in Mexico City, according to a report in the San Francisco Chronicle.The report found that only a fraction—83 of 2,000, or just over four percent—of pre-Columbian artifacts could be certified as “museum-quality” by an independent team of museum curators who came from Mexico City to conduct the test. The remaining 1,917 items are considered “decorative,” and will likely be given to schools or smaller museums ahead of the museum’s 2019 move from a temporary site in Fort Mason to a permanent home in a tower under construction near SFMOMA.
