This pair of Indonesian stamps, issued in 1949, commemorates the country’s independence following the transfer of sovereignty from the Netherlands. The design features a powerful image of a buffalo, a symbol of strength and resilience, set against a background map of the Indonesian archipelago. The inscription “RIS Merdeka” (“Republic of the United States of Indonesia – Freedom”) reflects the federal state briefly formed in 1949. Denominations shown are 50 sen (airmail) and 10 sen, both printed by Staatsdruckerei Wien (Austria). These issues are historically significant, marking the birth of modern Indonesia as a sovereign republic.
