Advice on Buying and Selling
Olivier Bertrand has negotiated works and sometimes masterpieces by numerous sculptors, from Rodin to Calder and Wouters, as well as numerous painters, from Renoir to Spilliaert, Van Rysselberghe, Magritte, and Alechinsky. But other, much less well-known artists have also caught his attention, the only condition being the emotion they are capable of evoking.
