[Below: Back of envelope. Note the words 'PULL OUT FOR POSTAL INSPECTION'. I found this to be rather odd, since the USA didn't censor any mail until its entry into WWII in December 1941. So why would the post office need to inspect it? Were they singling out the mail of the German Consulate? I wouldn't be surprised, since the USA had been supplying massive amounts of supplies and other assistance to Germany's enemies under the Lend-Lease program since September 1940 (officially, that is).]
