Dear Gregory,
Good morning, please find the following information regarding this Hummel figurine, "Carnival" from you mother's collection. In the case of this piece I would recommend selling it through an online venue like EBay, Etsy or Ruby Lane, these platforms have a history of selling Hummel ceramic figurines and have a global reach. Having the boxes will not only make them more desirable but easier to ship.
This is one of her more expensive pieces thus far. For each piece and/or set I've included the date name and descriptive details you should know about the piece. As always, let me know if you have a follow-up question regarding anything...

#328 Carnival, TMK-6, 1979 – 1991, with box

Regards,

Erin-Marie
