Unidentified Stamps

Here are some unidentified stamps to me. I think they come from Germany or occupied german territories, but no more idea :(
Help needed !
Thx

those don't look like postage stamps..
second one strikes me as part of a revenue stamp.
last two look like event or tourist stamps.. "come visit" type of thing...
Dresden.. the city that was fire bombed to ashes during WW2

Hi robinbouc - interesting stamps!

The first one appears to be a Prussian revenue:

K.PR. = Royal Prussian, Stempelmarke = revenue stamp.

The last one is intriguing. It appears to be a label from a German Colonial Exhibition of 1939 (!) in Dresden with a map showing the location of the former German colonies in German East Africa/Tanganyika, South West Africa and the Cameroons.

The first 2 are revenues.

Indeed. While Kurt Vonnegut was there as a US POW.

I visited Dresden in 1999, while restoration of the Frauenkirche was underway. Collected bits of rubble had been collected a cataloged ( quite a remarkable collection!) for the rebuild.

Reading now that the church on this stamp was not rebuilt allegedly because "…a socialist city does not need gothic churches".

I stopped there for a day while traveling, drawn mostly out of an interest in Vonnegut and JS Bach...

I would be very interested to know when that Dresden stamp was printed, even if it is a Cinderella...

I found interesting information about the "Kolonial cinderella" in this document (see page 30) :
