Mafalda's younger brother Guille is born and a new character, Libertad, appears. These new characters reflect the radicalization that was taking place in the world. In Argentina, political differences become larger, and Quino decides to put an end to Mafalda. But that end is a new beginning: through Mafalda's books, which are reprinted again and again, and translated into more than 26 languages, Mafalda's popularity grew exponentially.
