franked with three East China Liberated Area stamps, totaling 60 yuan, the correct international regular letter rate. Mailed barely half a month after the liberation of Shanghai, this aerogramme was posted during the transitional phase when the postal system of the East China Liberated Area had just been taken over but international airmail service had not yet been fully restored. Although nominally under the administration of the new People’s Post, postal operations at that time largely continued under the former ROC system to maintain overseas correspondence. The aerogramme was first sent from Kashing to Shanghai, then forwarded to Tokyo by the China National Aviation Corporation (CNAC), illustrating the integration of postal and civil aviation systems during the early phase of the new regime. Faint arrival markings dated late June confirm its transmission by air. This rare international aerogramme from the immediate post-liberation period not only shows accurate postage and clear chronological postal markings but also vividly documents the transitional operation of the East China postal system and the continuity of China’s foreign mail service. It represents an important postal artifact for studying the transformation of China’s postal system around the time of the founding of the PRC, with significant philatelic, airmail, and historical value.
