This 1966 Indonesian semi-postal stamp features the Reticulated Python (Python reticulatus), one of the world’s largest snake species, locally called Ular Santja. Printed in brown and green against a pink background, the design highlights the python coiled among grass. The stamp bears a face value of 2 Indonesian Rupiah + 0.25 surcharge, with proceeds often intended for social or cultural funds. It carries the inscription Republik Indonesia and shows a traditional emblem along with the year of issue. A striking addition for collectors of wildlife and herpetology themes.
