This stamp comes from the famous Junk Issue of the Republic of China, first released in 1913. It features a traditional Chinese junk ship sailing near the coast, a powerful symbol of trade, heritage, and resilience during the early Republican period. The inscription reads “Republic of China Postage” in English along with Chinese script above. Printed in green, this 4 cents value belongs to one of China’s most iconic definitive series, issued during a time of political change after the fall of the Qing dynasty. Used copies like this one, with clear postmarks, are particularly valued by collectors for their historical and postal significance.
