Cultural figures sign open letter asking government for clarity on how long landmark collection will remain abroad

One of the world’s most important collections of 20th-century Mexican art, including works by Frida Kahlo and Diego Rivera, is set to be exported to Spain under an agreement with Banco Santander, sparking outrage among Mexico’s cultural community.

Nearly 400 cultural professionals have signed an open letter calling on the Mexican government to offer greater clarity on what the deal means for the masterpieces, particularly the works by Kahlo, which the Mexican state has declared an “artistic monument”.
