'Mister No'.
Stefano and Domenico Di Vitto are two brothers from Scanno, Abruzzo, who work together on comic book artwork. Stefano does pencils, while Domenico focuses on the inking. They began their collective comics oeuvre scripting episodes of 'Mandrake' for Fratelli Spada. In the early 1970s, they created 'Joe Colt' in cooperation with the artist Dominico Mirabella for a Roman publisher. During the early 1970s, they worked for Ceretti on features like 'Zorro', 'Manilla', 'Il Santo' and 'Geronimo'. They then worked on 'Il Vampiro', 'Cimiteria' and 'Wallenstein' for Edifumetto, and did contributions to the magazines Intrepido (Universo) and Corrier Boy, and the comic book series 'Alan Ford' and 'Diabolik'.
By 1982, they joined the publishing house Cepim/Bonelli, where they started out alternating with Marco Bianchini on 'Ken il Trapper' strories for Piccolo Ranger from scripts by Tiziano Sclavi. They eventually became regular artists of the Bonelli series 'Mister No', which they continued to draw until 2008. They have since been active as artists of 'Zagor'. Domenico and Stefano Di Vitto have also made the first tourist guide in the comics format, called 'Viaggio in Abruzzo a Fumetti'.
