1943 Danzig Invite to Celebration of the Third Reich Governments 10 years in power 

I am gradually selling off my collection of German postal items and other German period items which I have collected over the past two decades. 

What types of German stamp/postal cancels, FDC, covers/envelopes, postal stationary and postcards do you collect as I might have what you want. Of course any sale would be via Ebay.
