This classic 20 Para orange stamp from Montenegro features a finely engraved portrait of King Nicholas I, the country’s long-reigning monarch and its first (and only) king. Issued in the early 1910s, it forms part of the definitive series showcasing royal regalia and national pride before Montenegro’s union with Serbia in 1918. Its ornate scrollwork and Cyrillic inscriptions reflect Balkan design influences of the period. A valued collectible for philatelists focusing on Balkan monarchies and pre-WWI European issues.
