1. Night of Long Knives (1934)
4. Kristallnacht (1938)
3. Auschwitz opens (1940)
2. Wannsee Conference (1942)
Now a couple of these were a little hard to place, for Auschwitz, I simply put the year in which it was first operational. I've placed the years by the side of each for your reference.
I would say paper.If it is not paper then it is silk.
