Drawn from one of the richest private collections of Latin American photography in the world (that of Stanislas and Leticia Poniatowski), the project Mutant Cities is a visual exploration of various cities in the region with an emphasis on their capacity for architectural, cultural, and social transformation, as modern theories and policies began to be consolidated in Latin America after the middle of the twentieth century. The project includes images by such masters as Paolo Gasparini, Geraldo de Barros, Horacio Coppola, and Fernell Franco, as well as other rediscovered talents who offer a universal view of many important aspects of the Latin American city, from night life, popular street culture, mass movements, and political demonstrations, to the contrasts between modern and vernacular architectures.
