This 1949 tax stamp revalued to 80 Chinese dollars features a violet Gold Yuan overprint applied to a prior 50-dollar blue and slate design, originally intended for fiscal use but repurposed for definitive postal service during the monetary transition of the late 1940s. Printed using lithography and issued ungummed, the stamp bears no watermark and displays variable perforation typical for emergency overprint issues of the time. The underlying imagery presents a symbolic triad of modern transport—airplane, steam locomotive, and ocean liner—emphasizing technological ambition amid economic instability. Issued during the waning days of the Republic of China’s mainland administration, these overprints reflect both inflationary pressures and the pragmatic reuse of existing stock for postal needs. This mint never hinged block of six retains full margins and original condition with bold violet surcharge and excellent centering. Cataloged as Scott IM924, Michel CN-IM 989, Yvert et Tellier CN-IM 758, Stanley Gibbons CN-IM 1130, and China Stamp Society CN-IM 1312. It stands as a vivid document of fiscal improvisation and transitional statecraft. Estimate "$95 – 115"
