375rd Heinrich Köhler auction - Day 1

1855, letter sheet addressed to Copenhagen, dropped in a letter box , endorsed "franko" in lower left corner, posted with Copenhagen compass mark of 24.11.1855, marked in red crayon "ubetaldt kassebrev" and charged with "8" skilling (instead of usual 3 sk. for unpaid local letter). Possibly because the letter is adressed in swedish, the postal clerk charged the 8 sk. Oresund rate; highly unusual
