The Invaluable Group is developing a product to helps art lovers establish the provenance of their prospective purchases.

Called Invaluable Checker, the database-driven product establishes the auction history of a piece of art - in some cases as far back as the 19th century by searching the unique Leggatt Archive.

The Leggatt Archive is a comprehensive collection of UK auction catalogues from most of the major fine art sales between 1836 until 1992, which have been carefully annotated with sale prices and names of buyers.

Invaluable Checker can help buyers and sellers in the auction world by preventing stolen items getting to market in the first place, and by detecting those that are already there, thus ensuring peace of mind for beginners and experienced collectors alike.
