Hallo, bent u daar niet?

In 1982, Het Spectrum published a single-issue Dutch comic titled Hallo, bent u daar niet?, a concise, standalone work that stands as a complete, self-contained statement from its era. While the series has remained at one issue, its existence marks a curious, singular entry in the publisher's catalog, notable for its abrupt, questioning title and its place within the broader landscape of early-1980s European comics.
