As a result of the Napoleonic wars, vast numbers of Old Master paintings were released on to the market from public and private
collections across continental Europe. The knock-on effect was the growth of the market for Old Masters from the 1790s up
to the early 1930s, when the Great Depression put an end to its expansion.This book explores the global movement of Old Master
paintings and investigates some of the changes in the art market that took place as a result of this new interest. Arguably,
the most important phenomenon was the diminishing of the traditional figure of the art agent and the rise of more visible,
increasingly professional, dealerships; firms such as Colnaghi and Agnew's in Britain, Goupil in France and Knoedler in the
USA, came into existence. Old Masters Worldwide explores the ways in which the pioneering practices of such businesses contributed
to shape a changing market.
