I absolutely love this music box. I requested the 'Superman' theme song by composer John Williams. The wooden box is simple but beautiful and sturdy. The music box is approximately 2 3/4 inches side to side, 2 1/2 inches front to back and 2 1/2 in height. But let me tell the sound coming out of this box is...well, SUPER. Thanks for a gift that I will enjoy for a very, very long time.
