Here are stamps issued by the Nationalist Government of China in 1947 called "Progression of the Postal Service". They issued a number of commemorative stamps in this year but this set show a mobile post office and a postal kiosk. I don't know if the scan is large enough (click to enlarge) but I do like the pointing hand on the pole by the kiosk. How wonderful to drive a postal van in the rural areas of China but possibly not in 1947 when the country was in the middle of a civil war, within two years the Peoples Republic of China was born.
