Issued in 1980 as part of the Europa stamp series, this Liechtenstein 40-rappen stamp features a finely sculpted portrait of Princess Marie Leopoldine von Esterházy, Princess of Liechtenstein. The elegant classical bust design highlights the artistic heritage and aristocratic lineage associated with the principality. Printed by Courvoisier and designed by Louis Jaeger, the stamp is admired for its refined engraving style and rich monochromatic green tones. Europa issues from Liechtenstein are especially sought after by thematic collectors focusing on European cooperation, royalty, and classical art portraiture.
