Postcard to the camp is much more unique than letters sent from the camp. Among other things, because the prisoners could not keep these letters, they only had to pass them when collecting the next one. For this please take into account the fact that there is a continuous lack of paper, for example for cigarettes, toilet, secret message etc. The envelope has a censor stamp. Correspondence is in half folded but nevertheless it miraculously survived and is in good condition.

Also we found in German archives few documents after him, copy below.
