The anonymity of buyers is also a huge advantage for criminals. Who hasn’t seen the images of an art auction for a famous painting at Christie’s or Sotheby’s, where brokers are on the phone with mysterious clients? Art market operators generally refuse to disclose the identities of their clients under the guise of “protecting the integrity of the transactions.”
Recently, some countries in Europe, including Luxembourg and Switzerland, have passed laws to clamp down on money laundering in the art market. Starting in 2016, Switzerland will cap cash transactions at 100,000 Swiss francs ($135,000). Payments above that cash limit will have to be made by credit card, creating a paper trail, or the seller will have to carry out due diligence to ensure the legal origins of the funds.
Despite those advances, the detection of fraudulent art remains a complex undertaking. It is particularly difficult to weed out forgeries in the work of modern artists whose large numbers of works and superstar statuses make them especially attractive to those who commit fraud. Pablo Picasso, for example, was a prolific artist, creating a huge number of works on canvas and on paper as well as sculptures and ceramics. Considering his vast output and the varying styles and media in which he worked, scholars have had difficulty establishing a definitive corpus for him. The prestige associated with owning a Picasso and the difficulty of attribution, especially for a drawing, made and continues to make fraudulent representations of his work hard to police.
