I know it's getting late for this, but these are actually my favorite of our Christmas decorations. I love them more than the tree. They were originally given to my mother by an uncle of hers (he gave sets to her and each of her two sisters) and she added to them to make sure that Auntie Chris and I each have a set. (Both of which live at my house for now.)
I think you can still get some version of them various places, including, of course, here. I like that they have star on the top of the tree instead of a Santa.
