Series "Arte público como plataforma de memoria cultural" is part of a collective project that seeks to link research and knowledge dissemination. The book "Huellas en los muros" focuses on the post-revolutionary murals made between the twenties and the early thirties of the 20th century. The interpretative essays seek to generate in the public new looks and sensitive and reflexive approaches that activate the interest to know the history and the development of the images that remain in the walls, as well as the historical, political, cultural and artistic context in which they were created. We are interested in illuminating areas that have been scarcely worked in the historiography on Mexican muralism and show that cultural and political processes are not homogeneous, rather operate through multiple frameworks that acquire different meanings. We invite you to take a visual tour of the variety of murals that formed part of this first posrevolutionary iconography that recall symbolic images, popular and realistic. Likewise, one can observe the experimentation that the young painters carried out with traditional techniques such as encaustic, fresco and tempera. Visiting these murals transports us to a time in the past that is reactivated with our contemporary perspectives, turning the space into a place of memory that unfolds interconnected and complex cultural processes through different layers of meaning.
