This stamp originates from the Republic of China and features a portrait of Dr. Sun Yat-sen, the founding father of modern China. The base design shows him framed with classical columns and the emblem of the Kuomintang at the top. Originally issued with a face value of 30 yuan, it has been surcharged with an overprint to a new denomination, reflecting the inflationary period of the late 1940s. Such overprints were applied during transitional currency reforms, making these issues significant for collectors interested in China’s turbulent postal and economic history. The mix of original engraving and bold surcharge gives this piece particular appeal within Sun Yat-sen definitive series.
