Rafael Gallur was born in Mexico City. He began his career assisting Zótico Fonseca and Carlos Mabridis and published his first work in newspaper La Prensa. He then worked for the publishing house Edar (later Vid) on comic books like Mini Terror, Mini Aventuras and Mini Policíaras, and for EJEA on 'Frank Kein', 'Posesion Diabolica' and 'Sangre India'. He eventually left the illustrations of comics to focus on cover paintings, among others for Sensacionales de Lucha, Vaqueros and Maestros under the pseudonym Garr. He later returned to interior art with stories for Arena, and inking jobs for DC and the 'Star Trek' mini-series. Gallur is an illustrator for the Ghetto Librettos (small Mexican pulp comic books full of sex and violence) by Editorial Mango, like El Pisolero, Guerreros del Ring and Guerreros Del Ring Especiales.
