Giovanni Benvenuti made his debut at the publishing house Mondadori, illustrating the comics adaptation of 'L'Ultimo dei Mohicani' in Topolino. Also for Mondadori, he illustrated several short stories for Gli Albi d'Oro. From 1950, he drew 'Buffaletto Bill' for Editrice Nika, and from 1955, he took on episodes of 'I Tre Bill' with scripts by Gianluigi Bonelli over at Audace. He was also active as a cover illustrator and painter. Initially influenced by Walter Molino, later by Americans like Eisner and Caniff, Benvenutti eventually developed his own personal style.
