Issued in 1969, this striking set from Liechtenstein illustrates traditional Alpine folk tales through modern, abstract art by Louis Jaeger. Printed by Courvoisier S.A., the designs depict vivid mythological scenes — “Der Schutz auf St. Mamerten” (30 Rp) shows a fiery red spirit chased by villagers, “Der Kobold im Bergerwald” (50 Rp) features a mischievous forest sprite, and “Drei Schwestern” (80 Rp) portrays the legend of the Three Sisters. The bold color palettes and stylized figures make this series a standout of mid-century European graphic design, blending folklore with avant-garde aesthetics.
