In 1931, Diego Rivera was the subject of The Museum of Modern Art s second monographic exhibition, which set attendance records in its five-week run. The Museum brought Rivera to NewYork six weeks before the opening and provided him a studio space in the building. There he produced five  portable murals  large blocks of frescoed plaster, slaked lime and wood that feature bold images drawn from Mexican subject matter and address themes of revolution and class inequity. After the opening, to great publicity, Rivera added three more murals, taking on NewYork subjects through monumental images of the urban working class. Published in conjunction with an exhibition that brings together key works from Rivera s 1931 show and related material, this vividly illustrated catalogue casts the artist as a highly cosmopolitan figure who moved between Russia, Mexico and the United States and examines the intersection of art-making and radical politics in the 1930s.
