bearing a single 10 fen Dr. SYS Hwa Nan Print basic currency stamp, tied by Canton cds “49.8.29”; although the second international aerogramme rate of 30 fen had been in effect from Jul 5,1949. This cover bears only 10 fen and is clearly underpaid. Nevertheless, it was accepted and transmitted without postage due or penalty, representing an example of underpaid mail tolerated without surcharge. Illustrated in Patrick Choy, China Silver Yuan Stamps (3rd Edition), page 33, Figure 1-14, this item reflects the flexibility of postal operations during the transitional adjustment of rates in the early Silver Yuan period, and demonstrates the continued functioning of international airmail routes from South China. A scarce international aerogramme exhibiting significant postal history and exhibition value.
