1897 Shanghai (17 Sep) to Mr. F Salzmann, Switzerland, f.w. Red Revenue surch large figre 4c/3c (Chan 89) for double printed matter rate, tied by Shanghai dollar cds. In combination with Coat of Arms 7k, tied by Shanghai Russian PO (4 Sep) with T&S type 1 cds in violet. Transit Shanghai BPO (18 Sep), Hong Kong (21 Sep). Arrived Bern (22 Oct). Despite philatelic given the addressee, single franking of Red Revenue 4c and combination with Russian stamps is very appealing. Combination with Russian stamps is the rarest combination for Red Revnue covers as there is only one example recorded in "The Revenue Surcharges China 1897" by Directorate General of Posts, ROC. 2024 (May-Jun) Interphila Auction, lot 806. With swissasia-philately certificate.1897.9.17 上海寄瑞士F. Salzmann，貼紅印花加蓋大字4分蓋3分（陳目89），銷上海大圓戳。加貼軍徽圖7戈比，銷上海俄局T&S 1型紫色日戳。9.18經上海英局，9.21經香港。10.22抵伯恩。從收件人可知為集郵封，但單貼大肆分並混貼俄國票實在稀罕難得。混貼俄國票為紅印花封片中最為稀罕少見之混貼形式，即使在交通部郵政總局《紅印花郵票》中亦僅見一例，可遇不可求。2024.5-6 Interphila Auction，拍品號806。附swissasia-philately證書。
