1943 WWII German Postcard with Cologne Postal Cancel- Ist Day of Stamp Issue

In good condition, no writing on front or back of postcard  

Within Ebay rules for German WW2 postal cancels on covers/envelopes/postal cards (Stationary) and permitted postcards.

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.
