This short film is the most famous Peronist propaganda piece, most likely due to the expressionist visual power of Pappier's imagery. It is based on a poem by José María Fernández Unsaín in which a couple of workers (Fanny Navarro and Pedro Maratea) compares a past of explotation and misery with the new Argentina of Peronist social justice.
