The brothers Carlos and Luis Fresno had a collective comics oeuvre under the pseudonym Fresno's. In the 1980s, they created the comic series 'Benito Boniato' at the publishing house Bruguera. They also did several albums of 'Astro Sniks', a comics adaptation of the toyline from the company Bully Figuren. When Bruguera folded, they joined Quirón Ediciones, where they illustrate books about military history.
