 In June 2003, Maitena began to publish the Sunday strip "Curvas peligrosas" in "La Nación".Unlike many fellow Argentine humourists (such as Quino in Mafalda, Caloi, Roberto Fontanarrosa or ), who rely on their characters' circumstances, Maitena focuses on the inner feelings of the female world.She is of Basque ("maitena" is Basque for "the most beloved") and Polish ancestry.
