This charming little music box plays "The Carousel Waltz" and is very reasonably priced. It measures 3 1/4" x 4 " x 2" high in its high grade very handsome opaque black case. The lid is not hinged but still controls the music. If fully wound, when the lid is off, the music plays and it stops when the lid is replaced.
The mechanism is viewable and there is a small space that measures 2 1/2" x 1 3/4" that could be used for a couple of rolls of stamps or a locket.
