Oscar Zarate has been an admirer of artists like Hugo Pratt, Milton Caniff, Frank Robbins and Bob Schoenke since his youth. He decided to become a very famous comic artist. He studied architecture and worked in advertisement before he left Argentina and moved to Europe. Zarate illustrated some children's books and made the comic adaptations 'Lenin for Beginners', 'Freud for Beginners', and 'Faustus'. After creating some short stories for several European magazines like Crisis! (stories with Carlos Sampayo), he made the popular comic 'A Small Killing' with writer Alan Moore.
