It wasn't until I got it in the car that I noticed the weird perforated top. Which puzzled me. And as I was pulling out of the parking lot an idea dawned on me, and it's kind of a miracle I didn't stop right then to test my theory.
Yes, a bottle brush tree in its own snowy little world. The snow shakes back into the perforated top, and when the music box is wound up, it falls. Ever so lightly. Sigh.
I may retire from thrifting. I'm never going to find anything this excellent again.
