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.
