Artist and proponent of the Mexican politico-social school of painting. TLS, two pages, 8.5 x 11, personal letterhead, June 25, 1957. In part, “To Arts (magazine) and all artists and men of culture in the world. My dear Sir: I address myself to you to ask that your voice and the authority of your position, reinforce the demand, in the name of everything in the world that signifies culture, beauty, joy and peace, for the immediate suspension of the thermonuclear and atomic bomb tests, since their continuation only can result in a general war with the consequent destruction of humanity…give a breathing spell in which men can recover their reason and arrive at an accord of the whole world for the prohibition of the manufacture and use of the thermonuclear weapon for the collective destruction of humanity.” Accompanied by the original mailing envelope. In very good condition, with Rivera’s handwritten initials on the front page, some light edge wear and scattered creases and second page affixed to a slightly larger sheet. R&R COA.
