カール・マイ
In the 1890s, there were Karl May clubs. Today, various entities focus on research about the author. These organisations exist in German-speaking regions, the Netherlands, Australia and Indonesia. While such societies are responsible for the release of most May-related periodicals, for example, "Der Beobachter an der Elbe", "Karl-May-Haus Information", "Wiener Karl-May-Brief", and "Karl May in Leipzig", the magazine "Karl May &amp; Co." is published independently.
