Ironically, I think I owned the same music box you described from your childhood. I can still hear the music it played when I opened the lid. Not sure what the melody was called that it played but I can still hear it.
The shop looks extraordinary! I think it would be a wonderful place to lose yourself in for hours! The detailing and intricacy of what you are describing is amazing to even contemplate!
I hope they were able to purchase something there as it would be a once in a lifetime opportunity! Thanks for sharing and have a lovely day!🤗💜 !LADY
