aww, she's super adorable! and the tune-playing function also sounds very cute
I don't think I've ever seen a doll like her before, so I can't offer help or information about her unfortunately
I hope someone else will know more about the line!
if you decide to make or buy preps like a bed for her, do take some pictures, I'd love to see her in a little setup made for her! ^^
ETA: I also did a google image search, and d'awwww, they are so cute! I'm not really into porcelain dolls, let alone collecting them, but I'm sure a doll like this would have come home with me too if I found one in a thrift store or second hand shop.
