Esteban Maroto Torres started his career in the early 1960s, working under the guidance of Manuel López Blanco in Madrid. Together with Carlos Giménez, he began an independent artistic career with such strips as 'Buck John' and 'El Príncipe de Rodas'. By 1963, he worked for the British market through Garcia Pizzaro's agency. He also worked through Bardon Art and Josep Toutain's Selecciones Ilustradas in Barcelona, illustrating series like 'Alex', 'Khan y Khamar' and 'Beat Group' in Spain and 'Alma', 'Capitain Terror', 'Die Funf von Terra' and 'Roy Tiger' for Germany (a.o. in Primo).
