These are really neat and took a lot of work. One is carved with what appears to be a cabbage rose and moth- the other has a lake mountain scene. The one with the cabbage rose does have a large hole just behind the scene that does not affect the picture. They both appear to have some age on them. The larger one is about 3.5" long and 2.5" high. What a great way to repurpose a discarded shell.
