My wife collects Christmas Tree ornaments. We have them in several categories. One year she might decide to primarily use special wooden ornaments purchased while we were living in Germany. Another year she uses a variety we have had from when our children were small. This year she decided to use mostly metal ornaments. The ones I like the best are from the White House Historical Association. Each year a new ornament is released for purchase. The one above is from 1998. Below, in order, are from 2017 and 2018.
