1949年12月22日中式銀圓封自廣西北流航空寄香港，背面貼桂區銀元票7枚，合50分銀圓，符合寄香港航空雙掛號郵資。北流鎮是南寧機場所在地，但飛機和設施在1949年11月中就已被遷走了。雖然這封信的航空郵資已付，但只能用快遞寄出。北流於11月30日已解放，此乃解放後沿用銀圓票的例子。 franked on reverse Kwangsi Silver Yuan x 7, total value 50c Silver Yuan, matching the Hong Kong airmail double registered postage. Peiliu is Nanning's airport town, but the airplanes and facilities had been removed since mid November 1949. Though airmail postage was paid, this letter could only be delivered by express. Peiliu was liberated on Nov 30. This is a post-liberation usage example of Silver Yuan.
