2 letters connected to KL Sachsenhausen Czech inmate. One was sent by the inmate called Franz Stuerak with number 30728 to a relative in 1942 in Protektorat Böhmen und Máhren, and the other letter is the answer to that letter sent to the inmate in the camp! Sachsenhausen letter comes with envelope and postal stamp and censorship ink stamp from KL Sachsenhausen. Letter is the typical stationery paper used for letters in that camp with red letter. Really good for reaserch!
