9/1940 WWII/Holocaust era mail from Palestine to Romania, undelivered & returned
Wartime outbound civilian mail: 1 SEP 1940 postcard from TEL AVIV to sender's mother at a Jewish institute(?) "Jüd Redacti" in PUTNA Romania, written in German, franked 10m per 8m overseas postcard rate & tied by single strike of local postmark; passed Palestine Censor T6(?) either on dispatch or return; unclear double-ringed transit mark on local postmark ( appears Soviet, without date-bridge); front-stamped 17 SEP arrival & numerous manuscript notations regarding Suceava country and Bucovina region, but as " address unknown" marked with local etiquette & dispatched back next day. This tiny locale was in South Bucovina near border with Hungary, an area which remained in Romania & not ceded to USSR in June 1940. Romania was then neutral but the Antonecu-Iron Guard government was established on 4 Sept & physical harm to Jews began 14 Sept. with an anti-Semitic Iron Guard campaign ( hence curious/distressing reason for postcard's return). Tear at top.
