Loredano Ugolini started his career in 1948 designing boys' jackets for Salani. Ten years later, the designer Erio Nicolo introduced him to the world of comics. Ugolini started a longtime cooperation with the Universo publishing house. After creating several episodes of 'Albi dell'Intrepido' and the 'Rocky Rider' western, he created his more popular characters. He started with the 'Billy Bis' comic, which appeared in Intrépido and later in its own periodical, Billy Bis Super. The scenarios are by Antonio Mancuso, with whom Ugolini also started the series about the controversial private investigator Cristal in Monello magazine. Among Ugolini's later series are such comics as 'Tony Gagliardo' (scenario Mancuso), 'Rox' (scenario Raffaelle d'Argenzio).
