Would appreciate any help in confirming the identification of a vase which appears to be Rosenthal & Co. I acquired the piece at an estate sale, and unfortunately don't have any information other than the markings that would help with identification. Photos are included. The vase stands at about 5" high.

I have a three piece set, loveseat settee and two (ladies and gents) parlor chairs that were my great grandmothers. The settee is darker green velvet and has a tag that simply says "style no. 43, cover no. 285 and VICTORIAN Montgomery, Ala.". The chairs are light green velvet and have no tags. They all have flowers carved on the top. I know they are earlier than 1970's. How can I tell who made them and when?

Bought at an estate auction with no history or background. Makers mark on the bottom resembles Ming Dynasty but could be a reproduction. Either way I am looking for a resale value.
I am very interested in what the translation is to the words on the back.

Also purchased 4 Liu LI Gong Fang glass sculptures I will list in a separate request.

A set of three collectors plate featuring illustrations that look french in origin.

Would anyone happen to be familiar with these items and know an estimate of their value?

Thanks you.
