This striking Indonesian stamp depicts a steamship in motion, originally issued in the early 1960s as part of a definitive maritime series symbolizing national trade and development. The design showcases Indonesia’s post-independence drive toward modernization and sea-based commerce.

In 1965, during a period of currency reform and postal rate changes, this 15-Rupiah value was surcharged in red with “Sen” and a pentagonal ‘65’ to indicate its new denomination for continued postal use. The overprint marks one of several transitional issues from that turbulent year, making it a sought-after variety among specialists in Southeast Asian philately.
