Pedro Alférez was born in the Baleares but he moved to Barcelona with his parents in the 1930s. He published his first comics in the 1940s including the series 'El Halcón de Acero'. Then he did such series as 'Conejín' (1945), 'El Rey de la Jungla' (1948) and 'Mascarita' (1949). 'Mascarita' was a heroine whose adventures took place in Mexico in the late nineteenth century. In the 1950s Pedro Alférez also worked in advertising. In addition, he became a member of 'El Micalet', a group of water-color painters. Later he took over the comic series 'El Inspector Dan'.
In 1958 Alférez moved to France where he stayed the next ten years. There he met numerous Spanish comic artists who had emigrated as well (Arnal, Batet, Monzón, Ribera, Laffond, Gabi, etc). After working for the magazine Nano et Nanette, Alférez continued the series 'Brik, le Corsaire du Roi' (created by Jean Cézard and drawn previously by Jacques Arbeau). In 1968 Alférez was an artist for the German series 'Fix und Foxi'. Then he returned to Spain and published in Strong and other magazines.
