Miguel Bernet Toledano, who signed with Jorge, began his comics career after the Civil War, in 1942. He worked for several publishers, until he finally joined Bruguera in 1947. For the publisher's magazine Pulgarcito, he created series like 'Melindro Gutiérrez', 'Leovigildo Viruta', 'El Vagabundo Mostacho' and 'Las Fascinantes Aventuras de Tallarín López', often in cooperation with scriptwriter Miquel Cussó.
A year later, he created 'Orlando Cucala' and his most famous character, 'Doña Urraca'. Jorge continued the adventures of this old man until his death in 1960. From then on, the comic was continued by several anonymous artists, among which his son Jordi Bernet.
Later series for Pulgarcito were 'Don Pancho' (1951) and 'Sisebuto, Detective Astubo' (1951). Jorge was present in El DDT with 'Sinforino' (1951), 'Ofelio' (1951), Chistes para Enclenques' (1951), 'El Mago Pirindola' (1950s), 'Don Pánfilo Tontáinez' (1959), 'Doña Filo y sus Hermanas, Señoras Bastante Llanas' (1959) and 'El Caballero Simón' (1960), and in Nicolás with 'Don Super' (1951) and 'Historias de cada Día' (1962).
He was also present in the girl's magazine Sissi, drawing 'Margarita Gutiérrez, la Dama de los Cabellos' (1958) and 'Nuestra Tía Enriqueta' (1958). Using the pseudonym Lucas, he did several contributions to the magazine Pepe Cola.
