AI Appraisal Estimate

A rectangular paper document titled 'Certificate of Authenticity' featuring a decorative guilloche-style border. The document is ostensibly associated with a lithographic print. According to the visible text, the document pertains to a work titled 'DEN MOTHER' by Guy Coheleach, reproduced by 'PETERSEN PRINTS' on September 16, 1987. The text describes a 'LITHOGRAPHY PROCESS' on '100% archival paper' with an 'edition of 1000 prints' and '50 copies designated as artist's proofs.' It bears a printed logo for 'PETERSEN PRINTS Masters COLLECTION' and a signature ostensibly from 'William L. Cooksey, Director.' The document appears to be mounted on a cardboard or brown paper backing and is housed within a protective sleeve. While the presence of this document is consistent with marketed limited edition prints from the late 20th century, the certificate itself is unverified without physical inspection of the paper quality and the corresponding artwork to confirm they constitute a matching set. The condition appears fair with some slight visible discoloration or surface marks on the left side near the logo.

I have examined the image provided of the document titled 'Certificate of Authenticity' for the print 'DEN MOTHER' by Guy Coheleach. Based on what I can see, this item is a piece of ephemera typical of mass-produced limited edition wildlife prints from the late 1980s. While it bears a signature consistent with a director from Petersen Prints, I cannot verify from a photo if this is a genuine signature or a printed facsimile. The document exhibits slight discoloration and surface marks, which is common for paper materials of this age. The value of such a certificate on its own is minimal, as it is intended to accompany the specific lithograph it describes. Without the corresponding artwork, this document serves largely as a reference piece or a replacement for a collector who already owns the print but lacks the documentation. I cannot confirm the paper quality or archival status without a physical inspection. Generally, in the market for wildlife art ephemera, such documents trade for very low amounts. The value estimate assumes the item is an intended accompaniment for the 1987 edition; however, if this were determined to be a modern reproduction or a copy of the original certificate, the value would be negligible. To confirm its status, an in-person examination of the paper's weight, ink absorption, and any potential watermarks would be required. The total value of the set (print and certificate) would be significantly higher, but as a standalone document, its market demand is restricted. For a high-confidence valuation, provenance linking this specific paper to the original Petersen Prints distribution would be necessary.
