ADOLFA HITLERA IN PRAGUE - ANNOUNCEMENT MARCH 15, 1939

This poster/document was apparently issued as part of Hitler's visit to Prague - you will note the largest and last stamp of this document shows the Nazi Swastika and I think it is dated March 15, 1939 the day Hitler arrived in Prague and annexed all of Czechoslovakia.

I do not know anything about the provenance of this poster/document - but it would be helpful if some one could identify the various dates on the cancellations - I assume they are all either March 17 or 18th 1939

Thanks for your help with this search.
