1872, 2 sen vermilion vertical pair, cancelled by black brush strokes on an unpaid cover, address side with small insect holes, inbound to Osaka from Kochi.

Manuscript date "5th month 14th day dispatched". Arrival large double-circle "Osaka Meiji 6.5..." (May to June 1873).

A scarce and highly interesting postage due usage, with the 2 sen pair applied to collect doubled unpaid postage under the unified tariff.

Rate: Letter 2 sen, unpaid and therefore doubled = 4 sen, nationwide tariff from Meiji 6.4.1.
