The glamour and mystery of the art auction, gathering interested buyers from across the globe, makes it one of the most fascinating marketplaces in existence. ‘Sleepers’, artworks or antiques that have been undervalued and mislabelled due to an expert’s oversight and consequently undersold, appear regularly. This fascinating new book provides the first extensive study of the phenomenon of sleepers through an in-depth analysis of the contractual relationships, liability and remedies that arise in the context of auction sales.
