This striking 1949 Chinese postage stamp features the portrait of Dr. Sun Yat-sen, the founding father of the Republic of China. Originally issued as a 20-yuan red definitive, it was later overprinted with bold black characters and a new 80,000-yuan denomination to reflect the rampant post-war inflation period. The “金圓” (Gold Yuan) overprint marks a transitional phase in China's currency reform during the late 1940s. A historically significant piece, it reflects both the political and economic turbulence of the era.
