1902 Mongtze B (Yunnanfu) (3 Aug) to Switzerland, f.w. Navigation and Commerce issue surch YUNNANSEN with Chinese value x5, tied by scarce Mongtze B French PO cds., along with R mark. Transit Haiphong (29 Aug). Arrived Moudon (10 Oct). With APS certificate. In 1900, Mengtsz and Yunnanfu were still not open to foreigners. French Indochina therefore set up the post offices in Mengtsz and Yunnanfu in the name of "Laokay A" and "Laokay B" respectively to keep a low profile. In 1901, Mengtsz was open to foreigners so "Laokay A" was changed to "Mongtze" while Yunnanfu was changed to "Mongtze B" until 1904 Yunnanfu was also open. According to AVA's record, about 20 covers from Mongtze B exist.1902.8.3 蒙自B（雲南府）寄瑞士。掛號封，貼航海及商貿神像改值YUNNANSEN連中文面值5枚，銷稀罕之蒙自B法局日戳，旁鈐R章。8.29經海防。10.10抵法國。附APS證書。 1900年，蒙自及雲南府尚未對外國人開放，故印支郵政在蒙自及雲南府的郵戳上，分別雋刻地名“老街A”及“老街B”以蒙混過關。到1901年，蒙自對外國人開放，故郵戳可改回“蒙自”，而雲南府則改為“蒙自B”。在1904年雲南府亦相繼開放，始使用正確地名。按艾華記錄，蒙自B寄出之信封存世約20件。 Estimates HK$ 7,000 - HK$ 15,000
