franked with nine East China Liberated Area stamps, totaling 180 yuan, equivalent to three times the 60-yuan international regular letter rate of the period. Mailed during the transitional phase following the liberation of Shanghai, when international airmail service had not yet resumed, the aerogramme took 46 days to reach its destination. Although marked “Par Avion,” it was most likely conveyed by sea. This cover illustrates how the postal administration of the East China Liberated Area continued to operate under the former ROC postal system to maintain international correspondence, reflecting the practical functioning of the postal service during the changeover between old and new regimes. A rare example of an international aerogramme posted on the eve of China’s political transition in 1949, it bears accurate postage and clear markings, and serves as an important postal history document for studying the continuity of postal operations and international communications during the late Liberation period of significant historical and exhibition value.
