The complete works of john Bunyan illustrated edition with written note inside signed by Bunyan and church members

Hi Clifford,

Thank you for contacting Mearto with your appraisal inquiry.

I've found a few copies of this volume available for purchase online, in the ballpark of $300, which would be a retail value; fair-market values such as those Mearto provides, are less, in the range of $100-150. In my research, I've discovered another copy (https://www.abebooks.com/first-edition/Complete-Works-John-Bunyan-Bradley-Garretson/31296858358/bd) that includes a facsimile of Bunyan's will, which appears to be the document that you have, though yours may be incomplete.
Based on the photos and information provided, and subject to examination, this is:
