Hi, my name is*****'m a certified appraiser, and I'd be happy to help.
Can you upload a photo of the cover, and of the title page?
Photo upload instructions are here:
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.
I've been trying and trying, but I've been unable to match the page styles to any of the known 17th century printed examples I can locate. The printing seems quite refined to be that early.
I'll need to see the cover and title page, or first few pages.
Sure, if for some reason the thread closes, you can ask Customer Service to reopen it.
