Republic of China Postage Stamp featuring Sun Yat-sen

This item is a vintage postage stamp from the Republic of China, featuring a portrait of Sun Yat-sen, widely regarded as the 'Father of the Nation' of modern China. The stamp has a primary color of a deep, muted green, with black ink used for the portrait and some of the text, set against a lighter cream or off-white paper base. The design is rectangular with an elaborate decorative border, giving it a neoclassical or formal appearance. The central motif is an oval-shaped bust portrait of Sun Yat-sen, depicted facing slightly to the right, with a serious expression. He is wearing what appears to be a formal collar and attire, characteristic of early 20th-century Chinese political figures. Above the portrait, centered within the frame, is a circular emblem resembling the Kuomintang (KMT) or national emblem of the Republic of China, commonly known as the White Sun in Blue Sky. Along the top border, Chinese characters are visible, likely denoting the country and purpose. Below the portrait, more Chinese characters are present, translating to '中華民國郵政' (Zhonghua Minguo Youzheng), which means 'Republic of China Post'. The denomination '4' is clearly visible in both bottom corners, indicating a value of 4 cents or fen. The full text at the top reads '分肆' (Fen Si), meaning 'Four Cents'. The stamp is perforated along its edges, which is typical for postage stamps, suggesting it was originally part of a sheet. There are visible signs of wear and tear, including what appears to be a cancellation mark or postmark across the upper right portion of the stamp, covering some of the border and Sun Yat-sen's forehead. This mark suggests it was used for mailing. The overall condition appears consistent with an aged, used postal item, showing some discoloration or foxing on the paper surrounding the stamp, part of a larger sheet or collection page. The printing quality indicates a level of detail appropriate for government-issued philatelic items of its era. This stamp likely dates from the period of the Republic of China before its retreat to Taiwan, specifically during the Kuomintang rule on mainland China.
