Iturbide’s MFA Boston show will be run concurrently with the museum’s “Frida Kahlo and Arte Popular” exhibition beginning on February 27th. It’s fitting that the two women will exhibit alongside each other, not just because they are among Mexico’s most important artists, but because Iturbide was allowed to photograph Kahlo’s bathroom in Casa Azul after it had been locked for over 50 years at the order of Diego Rivera, following Kahlo’s death. In a 2009 book called El baño de Frida Kahlo (“Frida Kahlo’s Bathroom”), Iturbide chronicled what Kahlo, who lived with chronic pain, left behind: containers of Demerol, a series of elegant yet confining back braces, a leg brace, a hot water bottle, a stained hospital smock. And yet, as with all of Iturbide’s work, the objects take on haunting austerity, saluting the life of another great Mexican artist in all of its vibrancy and pain. Much like Kahlo, Iturbide has spent a life finding the fantastical amongst the ordinary.
