"BREMEN 2/7" - blue K2 of the Hanover postoffice (with narrow letters, Knauer/salmon no. 164, time of use 1858-1866, in use on Prussia in the manual not listed) mounting marvelously clearly and ideally just as a task cancel buried on Prussia postal stationary 3, Sgr. Head issue (overexerted 1855) to Stettin, back issue cancel. Value cancel with a correct pen stroke devalues, no after-valuation or written non-recognition. This is a rare from outside use with full recognition of the postage long before Prussia annexed Hanover. "The rare mail item for once lets itself be seen in outstandingly good quality and is genuine" certificate Flemming BPP (12/2011.)
