LENZENHOF (Latvia): 10 kopeck brown and blue, large margined lower right sheet corner with about 5/6 mm sheet margins at right and base, tied by clear purple pre-philatelic double line "LENZENHOF 4 APRIL 1858" to lettersheet to Lemsal. The stationary paper cleaned and still some remaining staining, but altogether fine and attractive. The only recorded No.1-entire with this coloured cancellation and one of the most spectacular and important cover with a single No.1. Signed Emilio Diena and Alberto Diena, certificate Mikulski (1995, stating the address being improved)
