Pierre-Auguste Renoir Etching 'Sur la Plage' with Rudolf Lesch Fine Arts COA

This item consists of two vintage Certificates of Authenticity (COA) issued by Rudolf Lesch Fine Arts, affixed to the reverse of a framed artwork. The COAs identify the piece as an original etching titled 'Sur la Plage' by the renowned French Impressionist artist Pierre-Auguste Renoir. The certificates feature a green decorative guilloche border on aged, cream-colored paper. They include typewritten details and an authorized signature from Rudolf Lesch Fine Arts. The certificates appear to be on acidic paper, showing significant yellowing, foxing, and visible staining, particularly on the lower document. The paper is attached to a brown cardboard backing. A metal saw-tooth picture hanger is visible at the top edge of the frame. The presence of two identical COAs suggests either two separate impressions of the etching were handled or one is a carbon copy. Rudolf Lesch was a prominent mid-20th-century New York art dealer known for distributing prints, and these documents likely date to the mid-1900s. The etching itself is not visible in the frame, but the documentation suggests a restrike or a posthumous edition typical of Renoir's graphic works sold through such galleries.

I have examined the documentation for the Pierre-Auguste Renoir etching 'Sur la Plage' via the provided imagery. The presence of two Rudolf Lesch Fine Arts Certificates of Authenticity (COAs) on the verso provides a significant lead into the provenance of this work. Rudolf Lesch was a reputable New York distributor active in the mid-20th century, typically dealing in posthumous restrikes from Renoir's original plates. The documents show heavy toning, foxing, and acid migration consistent with mid-century cellulose-based papers, which paradoxically aids in dating the framing and documentation to the expected period. While these COAs increase the likelihood that the etching is an authentic posthumous pull (rather than a photomechanical reproduction), they do not represent a lifetime impression or a numbered edition. The market for Renoir restrikes remains steady, attracting entry-level collectors of Impressionist graphics. Comparables for 'Sur la Plage' restrikes with established gallery provenance generally sell within the high hundreds to low thousands. Demand is tempered by the high volume of these plates printed throughout the 20th century. Limitation: This appraisal is based solely on the documentation and not a physical inspection of the etching itself. To confirm the value, an in-person examination is required to verify the paper's watermark (likely Arches or Rives), plate mark dimensions, and ink saturation. This is necessary to distinguish a genuine etching from a high-quality facsimile. For absolute authentication, the etching must be removed from the frame to inspect the sheet's edges and reverse for further gallery markings or stamps.
