La Marcha de la Plena Verdad is Rosa Luisa Márquez's first graphic-theatrical collaboration with renowned visual artist Antonio Martorell. Created with Puerto Rican historian Lydia Milagros González, and with a turnout of over 120 participants, this public demonstration condemned the political intervention of the United States in Nicaragua. Willie Colón's "La era nuclear" is the theme song showcased in this video, which documents the diverse masks, puppets, banners and other artistic strategies developed by "Taller de la Escarcha" in order to claim a cease and desist of American political interventions in Central America.
