To locate art appraisers outside of North America, check the CINOA (Confederation Internationale des Negociants en Oeuvres D'Art) website.
An art library may also be helpful for auction prices. Check for other works by this artist in Mayer, an annual two-volume publication that lists works of art that have been sold at auction internationally. The Art Newspaper printed a list of auction sites in its April 2000 issue, and the AskART.com website also has auction records and references.
Thank you for your interest in our collections, and good luck with your search.
