How interesting! We have a whirligig from Norway. It's wood and has three deer in different positions so when it goes around, it looks like one deer moving. There are candles on the corners, and the rising hot air makes it go around. The propeller blades on top are awfully scorched but I set it up every year enniway.
That's what we call a Christmas-Pyramid. I have two or three of them. They come in many different sizes and shapes; small, big, with only one story or two, three or four, with different themes, etc.
See the tree in the middle of the middle photo? This is a very typical work from the Erzgebirge (Ore Mountains). The tree is made from one piece, which is worked on as if it were a lemon and you want to make lemon zests. Or butter reels. Only you don't cut them off, but leave the rolled-up end on the pice. Then the next one, and so forth.
My father came from that area, so my grandparents used to send such stuff.
