Strange Wooden and Paper Box with a 3-d Victorian Mansion Scene Under Glass

I have a strange little box. It measures approximately 4.5 x 3.5 x 2.5 inches. It has a 3-d, what I will call, Decoupage scene under a thin hard plastic or glass. The scene is of a Victorian Mansion and country scene. It is a wonderful little box. There are no markings. Nothing at all as to how old it is. Don't know if it is a rare thing. Has someone seen anything like it before? Could even be a trinket box. Can't really call it a shadow box.
