Frida Kahlo 2012 Calendar. This stunning Frida Kahlo de Rivera 2012 calendar features 12 stunning artwork illustrations celebrating the work of the Mexican painter who is perhaps best known for her self-portraits. The Mexican and Amerindian cultural tradition are important in her work, which has been sometimes characterized as Naïve art or folk art. Her work has also been described as ‘surrealist’, and during 1938 André Breton, principal initiator of the surrealist movement, described Kahlo's art as a ‘ribbon around a bomb’.
