franked with three 1 fen Dr. SYS Hwa Nan Print Basic stamps overprinted in black with “Mienyang,” together with three 4 fen surcharged revenue stamps used as Basic postage overprinted in red with “Mienyang,” making up the correct 15 fen airmail rate to Hong Kong, all tied by Mienyang cds, This cover is a representative example of the Silver Yuan period practice of local post office name overprints applied to different types of Basic stamps, here showing both black and red “Mienyang” overprints used concurrently. It reflects the complexity of stamp supply and control under the disordered currency conditions of the time, when such overprints were introduced to restrict inter-district usage, embodying a distinct regional postal system characteristic. According to current records, this is the only recorded cover bearing “Mienyang” overprinted stamps sent to Hong Kong, of exceptional rarity, combining significance in both external postal routes and the study of local overprint practices, and of considerable postal history and exhibition value.
