Deppen müssen draussen bleiben!!

A one-shot comic from 2004 by German publisher Niemann, Deppen müssen draussen bleiben!! (roughly "Fools Must Stay Out!!") is a standalone, single-issue gag strip. Its premise and characters remain minimal by design, as the title itself suggests a blunt, no-nonsense barrier to entry. The work is most associated with its creator, whose name is synonymous with the Niemann imprint, and it stands as a brief, self-contained curio in the publisher's output.
