1896年8月17日汉口寄上海封, 贴第二次加盖改值票一分于三角洋钱票一对, 销橙红色汉口工部日戳, 封背盖另一枚相同的汉口工部日戳, 旁有不太清晰的红色上海工部到达日戳, 这是该加盖票的发行首月封, 亦可能是存世唯一贴用第二次加盖改值票之实寄封.Hankow Covers 1896 (17 Aug.) envelope to Shanghai bearing pair of second provisional 1c. on 30c., horizontal surcharge [2-3] tied by a light strike of the Hankow Local Post c.d.s. in orange-red, a further strike on the reverse along with a poor strike of Shanghai Local Post c.d.s. in bright red. This is a very rare franking on cover with no other covers recorded, a very early date of used of this provisional which was issued in August 1896. Photo
