Very rare letter sent by a Jewish nobleman called Grafin Seipio del Campo to the American Commission for Polish Relief located in New York. This letter is particularly rare because it was sent from the Jewish Ghetto of Warsaw, and it wasn't allow to send letters inside envelopes. They could only send postcards for censorship reasons. This one has the ghetto censorship stamp from Warsaw Ghetto on left corner. Maybe this man managed to send this letter due to his nobleman condition. A very rare letter indeed!
