This Indonesian definitive stamp, valued at 7.50 Rupiah, features a detailed monochrome green vignette of a female telecommunications operator working at a teletype or early communications machine—an homage to Indonesia’s growing modern infrastructure in the mid-20th century. Issued as part of a broader series highlighting national development, the design captures both the era’s technological progress and the important role of women in public service. Printed in a clean typographic style with REPUBLIK INDONESIA along the bottom, it remains a sought-after item for collectors specializing in Asian definitives, technology themes, and post-WWII Indonesian postal history.
