This striking high-denomination definitive stamp from China (People’s Republic of China) features a bold engraved portrait of Chairman Mao Zedong, rendered in classic monochrome line work. Issued during a period of significant monetary adjustment, the 1500 Yuan face value reflects inflationary or currency-transition usage, making it a notable example of late-era definitive postal history. The vertical Chinese inscription identifying the People’s Republic underscores its strong political symbolism. Printed on coarse paper with simple perforations, this issue is sought after by collectors of Mao portrait stamps, PRC definitives, and high-value postal issues from transitional periods.
