'Artworks of very different kind may be misattributed by auction houses. Fakes by Han van Meegeren may be sold as works by the forged master Jan Vermeer; works of the workshop of Rembrandt may be offered as masterpieces of Rembrandt himself; and Sleepers by an unknown artist of the Renaissance period may be finally attributed as the portrait of Pope Clement VII by Sebastiano del Piombo. In all these cases of misattribution the question has to be answered whether the auction house is responsible for this misattribution and to whom. Anne Laure Bandle diligently treats all these problems in a comparative analysis of Swiss, English and US-American law and makes valuable proposal how auction houses should deal with their responsibility (authenticity guarantee) and which tribunal or mediation centre should decide issues of controversy.' --Kurt Siehr, Max Planck Institute for Comparative and International Private Law, Germany'This is an urgent appeal to all those acting within the complexity of today's art market and a brilliant vision on how to approach and resolve one of its pre-eminent problems, the issue of authenticity.' --Friederike Grafin von Bruhl, K&L Gates LLP, Berlin

'The pointed research and analysis of a worrying part of the trade, bound only to grow. Anne Laure Bandle has the breadth of knowledge and experience, investigative inclination and critical approach required to pen a fascinating book. With that, comes a joy at the world of cultural property that make her work an enjoyable read.' --Bruno Boesch, Froriep LLP, London
