Gallieno Ferri was an Italian comic book artist and illustrator. In 1960 Ferri met writer Sergio Bonelli and they created the comic book Zagor. Ferri illustrated the series from the first issue, drawing numerous stories. He also drew all the covers of the regular series. In 1975, Bonelli launched another series, Mister No, for which Ferri worked as a cover artist. Other characters created by Ferri include Maskar, Thunder Jack, Jim Puma and Capitan Walte.
Ponovni povratak Zagoru nakon dječačkih godina još me jednom uvjerio koliko se odrastanjem mijenja precepcija pročitanog. Ono što je još uvijek ostalo dobro u ovom stripu jest izvrsna animacija, dorađena do detalja i rijetko joj se mogu podkrasti grube pogreške.
