This green-toned definitive from Republic of Indonesia depicts a woman operating industrial machinery, symbolizing the country’s early post-independence push toward modernization and economic self-reliance. Issued in the 1950s–60s period, these work-themed definitives highlight everyday national productivity and social reconstruction. The clean engraving, monochrome style, and high face value of 7.50 make it a desirable piece for collectors of early Indonesian republic issues. Well-centered examples with fresh color remain particularly appealing in definitive-series collections.
