3070 – ERIVAN X

2c brown, block of ten, pair, and single, cancelled in manuscript, the single and pair tied by double-circle "Hiogo / Japan" c.d.s. to cover to Siegen, Rheinish Prussia, endorsed "via S. Francisco", where the block was cancelled with Nov 18 c.d.s., red "New York Paid All / Br. Transit / Nov 26" c.d.s., German c.d.s. receiver (8 Dec) on reverse, cover opened for display, one adhesive creased from being affixed over bottom edge, some edge flaws, but a remarkable and rare franking; with 1997 Philatelic Foundation certificate.This cover, being undated, leaves the rate open to some conjecture. If sent in 1869, it is a 1c overpayment of the  25c rate, being 10c per 1/2oz from the United States to Prussia via New York, and 15c for Prussian closed mail via England. If sent in 1870, it is a six cent overpayment of the 10c transpacific and 10c transatlantic rate. If the latter, one would assume the sender would have simply used the block of ten, unless the earlier rate was still in mind.
