[3] During the 1960s the duo became a mainstay of Italian comics creating successful series such as Kriminal and Satanik (1964), Dennis Cobb, Gesebel (1966, only first six stories by Magnus) and Maxmagnus (1968).
After leaving Alan Ford in 1975, Magnus began an association with Renzo Barbieri's publishing house, which specialized in the erotic comics genre.
Milady, translated also in France on Metal Hurlant magazine, is a science fiction series where Chinese culture, Flash Gordon and Star Wars' influences, erotism and technology are well mixed.
In 1989 Magnus began his last work, a long story featuring the popular Italian western character Tex, written by Claudio Nizzi: for it Magnus completed 223 exceedingly detailed plates in 7 years of work, for which he used original sources for any historical element, and studied from live any natural detail such as leaves, light and trees.
In August 1991 Magnus had moved to Castel del Rio, near Bologna, where he spent his last years and died of pancreatic cancer just a few days after completing his Tex story.
