This 0.50 Franc stamp from the Malagasy Republic (République Malgache) features the butterfly Salamis duprei, a species native to Madagascar. Issued in the early 1960s, the design highlights the butterfly’s striking blue and brown patterned wings, engraved with fine detail. The inscription “Fahafahana – Tanindrazana – Fandrosoana” (Freedom – Fatherland – Progress) reflects the national motto after independence from France in 1960. Designed by Munier, the stamp belongs to a series celebrating Madagascar’s rich native fauna and natural heritage. A desirable item for collectors of African, butterfly, and thematic nature stamps.
