Ghetto Warsaw - Rare registered letter sent by a Jew from ghetto Warsaw to USA. Very interesting envelope sent by Estera Pinkiert from Warsaw with ghetto censorship ink stamp to Jay Holdsheim in Chicago USA. This is quite unsual letter because Jews WERE NOT ALLOWED to send registered letters and neither they could send letters in envelopes! So we are in front of a very particular and rare case. Of course some existed but it was very rare. Very recommended very selective collectors of Holocaust related postal items.
