Hi, my name is*****'m a certified appraiser, and I'd be happy to help.
Can you also upload a photo of the mark?
Sorry forget that message! It posted to the wrong question.
Can you upload a photo of the bottom, so I can see construction?
I'm so sorry, I was out on emergency calls (fire-damaged artwork) yesterday and will be this morning. I will answer your question the minute I get back in the early afternoon.
So sorry, I meant a photo of the underside of the chair. I need a clear, well-lit photo of the underside to see the construction method.
