Official Auslandbriefprüfstelle Berlin (Foreign Mail Examination Office) correspondence, postmarked Berlin-Charlottenburg on 1st December 1941, and addressed to Frau Tiedemann, Wesermünde, Berckumerstr. 36. The accompanying official document reads: “2 postage stamps. Removed from your letter dated 26th November 1941 to Zahnleiter, Brooklyn, N.Y., U.S.A. The export of postage stamps without an export permit is prohibited.” It then cites the relevant German regulations governing the prohibition of the export and import of goods, including the Order of 27th March 1939 and subsequent amendments of 1939 and 1940. The document therefore records the actual intervention of the German authorities: Frau Tiedemann had enclosed two postage stamps in a letter to the United States, which were discovered and removed during examination of the foreign mail because she did not possess the required Ausfuhrbewilligung (export permit). The surviving envelope and explanatory document provide particularly direct evidence of German wartime controls over the international movement of philatelic material. The timing adds further historical interest: the original letter was posted on 26th November 1941, and this notification was sent on 1st December 1941, only ten days before Germany declared war on the United States on 11th December 1941.
