Although Groucho Marx has been protected by the US copyright law, one must always keep in mind that Dylan Dog was written in Italy, therefore in Europe, where the US copyright law simply doesn't apply. His character was replaced by Felix, yet somehow I prefer a much more interesting & a lot funnier Groucho. The purpose of this forum is to establish what does the majority of Dylan Dog's fan all over the world thinks on this subject, therefore the question from a title stand.
