This 1949 tax stamp from China features a red Type VI surcharge of 50 Gold Yuan on the original 300 dollar green issue. Issued as part of the tax series repurposed for definitive postal use, this stamp illustrates key modes of transport, including railways, ships, and aircraft, symbolizing the nation's infrastructure under transition. Printed by Dah Tung Book Company in gravure, the stamp has no gum as issued and shows the definitive Type VI characteristics—specifically the absence of a serif projection on the surcharge. Presented here as a bottom-right corner block of four with pristine perforation and strong color contrast, it is catalogued as Michel CN-IM 1005, Scott CN-IM 923, Yvert et Tellier CN-IM 780, Stanley Gibbons CN-IM 1147, and China Stamp Society CN-IM 1326. The block is in mint never hinged condition, exceptionally fresh and well-centered. Estimate "$85 – 105"
