envelope, From: Wieczorek, Jadwiga To: Bando, Stanislaw in Krakow (Poland) - Ravensbrück July 1943

Some envelopes have an illegible postmark but were put together with the letters they contained originally and which show the same block number. Since inmates were only allowed one letter per month in Ravensbruck, the manuscript date on the letter only contains the month and the year (and not the day).
