This 21-cent brown stamp from the Netherlands Indies features a beautifully engraved rural scene showing a farmer guiding a buffalo-drawn plough through lush tropical fields, with mountains rising in the distance. Issued in the late 1930s, this design is part of the iconic definitive series celebrating daily life and agricultural heritage of the colony. The fine line engraving captures both the landscape and traditional farming methods with remarkable depth. Postally used examples like yours carry strong historical character, reflecting real postal circulation in the Dutch East Indies before WWII. A desirable classic for collectors of Southeast Asia, colonial history, and engraved pictorial definitives.
