Welcome to JustAnswer, I am Rarewares and I will respond back as soon as I research your question.Please use the Add Files feature on your screen to add pictures of a signature and let me know a bit more about this piece (size, where you acquired it, etc).
I did respond asking for a bit more information from you before I answer. Is there a signature, if so, please add a photo. I would also like to know the measurements and where you acquired the piece. These are all standard things that an expert would ask before giving an assessment.
