Letter docketed Kronburg 26 Dec (1850) sent to Kiel. A fascinating letter with censorship “Efterseet af kommandantskabet / over Kronborg Fæstning / Signatur” with full contents preserved. The letter is written by a professor son writing to his parents and making reference to other military persons also at the Kronborg castle. A most unusual military censorship at Kronborg and at the same time also with cachet “Segel der Polizei Amts in Kiel” on the reverse. Extremely rare.
