1949 Shanghai (12 Oct) to USA, f.w. East China Area 22nd Anniv of PLA $370, tied by Shanghai bilingual cds. On 1 Oct, East China People's Post raised international letter rate from $180 to $370 but this rate only lasted for 39 days until 9 Nov as it was further raised to $500.

1949.10.12 上海寄美國，貼華東區解放軍二十二週年370元，銷上海三格漢英日戳。華東人民郵政於10月1日將國外平信郵資從170元提升至370元，但僅維持39天，並於11月9日再次提升至500元。可見此例甚為難得。
