A beautifully engraved mid-century Malagasy wildlife stamp featuring the striking Salamis duprei butterfly, rendered in elegant two-tone brown and blue. The symmetrical wingspread and scientific style highlight the island’s rich endemic fauna, a key theme in Madagascar’s classic nature issues. Fine line engraving by Munier gives the design crisp detail and strong contrast, highly appealing to topical and entomology collectors. The 0.50 franc denomination makes it part of the accessible yet collectible lower values of the set. A charming addition for butterfly, fauna, or African philately collections.
