This 0.50 franc stamp from the Malagasy Republic (République Malgache) was issued in 1961 as part of a beautifully engraved series showcasing native butterflies. The design features the Salamis duprei, a striking butterfly species endemic to Madagascar, with intricate wing patterns in shades of blue, black, and maroon. The inscription along the top—Fahafahana, Tanindrazana, Fandrosoana—translates to "Liberty, Fatherland, Progress," the national motto. Designed by Munier, the stamp reflects Madagascar’s rich biodiversity and its early philatelic celebration of local fauna following independence in 1960.
