TAIWAN HOT WEATHER POSTAL MARKING

Ai Li-Shan

In the late 1960s and early 1970s some post offices in Taiwan applied an interesting marking to covers concerning mailing in hot weather. Figure 1 and 2 is the front and back of a cover from Taipei to Taichung, mailed July 2, 1970. On the back of the cover in violet are three lines of characters, figure 3 that reads as follows: “When the weather is too hot, food easily spoils, do not mail”. This is a rather obscure marking. Since it was not a marking applied to philatelic mail, probably few were saved.
