Enric Sió was a cartoonist, illustrator, publicist and a photographer. 

  Getting his start under the Selecciones Ilustradas agency, his experiments with visual and aesthetic innovations on series such as Aghardi and Mis Miedos (translated in France by Dargaud), spanned his career before culminating in his most surrealist work, Mara.

  He also lived and worked in Italy and France, working on titles such as Lord Shark, Histoire de France and several episodes of the series "Grandes Héroes". He returned to Barcelona in 1979, where he wrote short stories such as Cuestión de Fé, Finisterre and Solsticio de Verano for the magazine Rambla. After failing as editor of the magazine La Oca, he devoted himself mainly to a role in the renaissance of Spanish comics, with an often pictorial style, experimenting with artistic and narrative resources.

  Committed to comics as an artistic expression, he played advertising and photography from 1985 onward. In 1971, he won the prestigious Yellow Kid Award in Lucca for Best Foreign Artist.
