A striking red Europa issue from Liechtenstein, featuring the symbolic key motif of CEPT, representing unity and cooperation among European postal administrations. The bold geometric design frames the letters C.E.P.T. within an ornate key head, combining modern graphic style with classic engraving. Printed by Courvoisier S.A., known for exceptional sharpness and rich color depth, this issue stands out for its clean lines and vibrant presentation. The large “50” denomination and strong contrast make it highly display-friendly in Europa or thematic Europe collections. A desirable piece for collectors of Europa, political history, and symbolic design stamps.
