complete stories in 100+ black and white pages in a pocket book format. The subject matter was always adventure, whether western, horror, mystery or science fiction. The bonelliani are to date the most popular form of comics in the country. Some of the series that followed Tex Willer were Zagor (1961), a tomahawk-wielding hero who protects the imaginary Darkwood forest in eastern US, Comandante Mark (1966), featuring a soldier in the American independence war, and more recently Mister No (1975), about an American pilot who operates a small tourist flying agency in the Amazonian jungle, and Martin Mystère (1982), featuring an anthropologist/archaeologist/art historian who investigates paranormal phenomena and archaeological mysteries. Another popular series, Diabolik featuring a criminal mastermind, has been published since the 1960s, and influenced later series such as Kriminal and Satanik (see Fumetti neri). The latter was created in the 1960s by one of the most famous duos of comics history, Magnus & Bunker, whose most outstanding creation, however, is the humorous espionage series Alan Ford (1969). Another famous author of humouristic strips is Franco Bonvicini, whose Sturmtruppen met wide success abroad. In the 1970s and early 80s, many young intellectual artists centred around the famous student city of Bologna began to be influenced by the underground comic scene of the United States, typified by the work of Robert Crumb. Artists such as Andrea Pazienza, Filippo Scòzzari, Stefano Tamburini, Tanino Liberatore, and Massimo Mattioli published stories with dark and surreal themes, ranging from political activism, to struggles with drug addiction and the disagio and disillusionment of youth culture in Italy. Many of the comics were extremely violent and sexual and attempted to stretch the comic genre to its vary limits in both style and "good taste." Satirical magazines such as Frigidaire and Il Male often printed these stories in episodic formats or as vignettes in their monthly publications. Though read by a more restricted audience, in the past years comics series with the greatest critical success are Corto Maltese, by Hugo Pratt, and Valentina by Guido Crepax. While the former is a kind of summa of the evolution into an adult form of the classic adventure comics, the latter gave birth to that special kind of erotic comics quite typical of the Italian scene, and whose main pupils have been in more recent years Milo Manara and Paolo Eleuteri Serpieri. Disney Italia Italy also produces many Disney comics,
