Public auction #38

1918, the probably unique 6 C. overseas usage: stationery card 1 1/2 C. on 1 C. uprated 1 C., 4 C. canc. "TIENTSIN B.P.O. SP 25 22" to Reichenbach im Vogtland/Germany. The 4 C. pasted slightly overlapping w. respective crease and 1 mm closed tear, backed. Less than a handful real commercially used copies are reported of this card, however most recorded usages appear cto.
A usage of the 6 C. overseas card rate from the ports (1 Jan 1922 till closure of BPO Nov. 1922) seems first reported. Other 1922 usages of this card are are uprated to only 4 1/2 C. and probably not mailed. Note that no 1/2 C. stamps were available and a "correct uprate" of a 1 1/2 C. card was not simply possible. Among the great rarities of the BPO in China ovpt. series.
