Opinions and valuations
The National Portrait Gallery is not able to give valuations or to recommend specific commercial organisations. For more information about the scope of our opinions service please see Statement of the scope and purpose of our opinion service and staff research on non NPG portraits. For advice on the valuation of works of art you should contact an auction house.
