De wereldreis van Rik en Klaartje

In 1982, Dutch publisher De Harmonie released the single-issue comic De wereldreis van Rik en Klaartje, a charming one-shot written by Willem and illustrated by the celebrated artist Joost Swarte. This concise travel adventure showcases Swarte's distinctive, clean ligne claire style, marking an early collaboration between two notable figures in Dutch comics. Though the series consists of just one issue, it remains a fondly remembered, self-contained gem from the Dutch comics scene.
