E pericoloso sporgersi

A single-issue comic from the Italian publisher Futuropolis, E pericoloso sporgersi (1988–present) stands as a singular, open-ended work. Its title, meaning "It is dangerous to lean out," suggests a cautionary or boundary-pushing theme, though the series itself has remained a lone, self-contained statement. While no creator is credited in the available facts, its significance lies in its unusual status as a series that began with one issue and has continued indefinitely without further installments.
