This watercolor had been on a mat that transferred acids to the paper and caused staining. Chemistry baths neutralized these stains, and after plenty of careful scraping we were able to remove the mat. There was some discoloration below the central trees that in-painting was able to restore. Acid-free, double mats then dressed up the painting and UV-filtering added protection. It was then re-fit inside the client’s frame.
We had hoped to discover the artist’s identity, but we were unable to do so. The only notation given by the artist was North Reigate, Surrey, which is a rather charming county south of London, but unfortunately none our cleaning efforts revealed a signature.
