cover 1900-01 Tientsin Provisional, 10pf. carmine horizontal pair, the right side stamp showing clear doubling of the handstamp, affixed to 1901 (14 Aug.) "Feldpost" cover from Tientsin to Germany (15.10.01 arrival backstamp), and cancelled by c.d.s.; left side stamp with 3mm tear at foot and envelope with some surface scuffs, however, a very rare error to find on cover and a late usage of this issue.
