This 3 Francs stamp from Luxembourg was issued in 1978 as part of the “Conservation de la nature” (Nature Conservation) series. It beautifully depicts the Pasque Flower (Pulsatilla vulgaris), a delicate violet alpine blossom known for its silky petals and early spring bloom. The design emphasizes environmental protection, promoting awareness of native flora preservation. Printed by Courvoisier S.A., the stamp combines botanical accuracy with elegant pastel tones against a sky-blue background. A fine example of Luxembourg’s ecological-themed philately from the late 1970s.
