As U.S. economic interests in China increased, the U.S. Postal Agency in Shanghai requested a supply of stamps that could be used at local post offices. At the time, the exchange rate between U.S. and Shanghai dollars was 2:1, and a series of Washington-Franklin stamps were officially overprinted by the Bureau of Engraving and Printing. These were placed on sale on July 1, 1919. After World War I, provisions were made to close almost all foreign post offices in China. The U.S. Postal Agency in Shanghai closed after December 31, 1922.
