A Brazilian Nazi Cover??

I like this cover for the Condor stamp on the front. But I googled the back stamp of Nieling and CIA. I found references to the Nazi party in Brazil. Problem is most info is in Spanish.
The addressees are, I think, a German manufacturing company. Problem is most info is in German.

Any thoughts or information on this, anyone?

Looks like a first flight cover to me.

To me it looks like a commercial air mail cover sent via Condor. The handstamp on the left looks more like a service handstamp rather than any commemorative event. One would have to research the history of the flights.

As for language barriers, do your searches through Google. In many cases you should be given the option of translating the website into English regardless of the language - German or Portuguese.

A lot of Germans immigrated to South America so no surprise about any connection and for awhile before WWII Hitler and the Nazi party was admired by many worldwide including some in the U.S.

I could find nothing on Google about the connection between Nieling & cia(co.) and the nazi party. Can you give more details?

I think I may have jumped the gun on this one. My research skills are lacking....

Putting the two together reminds me of the Boys from Brazil movie.

Great movie, lots of suspense and the actors, wow.

Gregory Peck, Laurence Olivier, James Mason,Lilli Palmer,
what a superb cast of actors.
