This pair of 16-cent brown stamps was issued in 1943 as part of the definitive wartime series portraying Dr. Sun Yat-sen, a foundational figure in modern Chinese history. Printed by the Central Trust in Chungking during the height of World War II, the stamps bear a bold red overprint reading “C.T.” (Central Trust) in traditional Chinese characters, denoting restricted postal usage under special administrative oversight. The design features Sun Yat-sen in formal dress beneath the Kuomintang sun emblem, framed with classic scrollwork and the denomination written both numerically and in characters. Typography was used for the printing on unwatermarked, thin wartime paper. These stamps were typically issued without gum due to material shortages during the conflict. Perforation is variable, as was common with emergency printings. Themes include revolutionaries, national leaders, and freedom fighters, and the stamps are a tangible reflection of wartime postal policy and symbolic state legitimacy. While not always catalogued in standard references like Scott, the item is of notable interest to collectors of WWII-era Chinese philately. Estimate "$80 – 120"
