Forgers of older artworks sometimes attempt to override forensic methods by using or plausibly imitating authentic materials. One of the best-known cases is that of forger Han van Meegeren, who used a modern paint mixture but mimicked an older technique to a sufficient degree that his paintings were certified, as he intended, as originals by the 17th-century Dutch master Johannes Vermeer. Even though further testing can reveal that a paint’s age has been masked, museums and collectors often simply accept initial results.
Of course, certain countries already impose AML regulations on the art world. The European Union Commission issued its 5th Anti-Money Laundering Directive in June 2018, which must be implemented by Member States by January 2020, and which in part expands its coverage of “obliged entities” to persons trading in art, acting as intermediaries in the trade of art, or storing art in freeports, if the value of the transaction or a group of linked transactions equals €10,000 or more. In the United States, although the BSA already applies to dealers in precious metals, stones and jewels, and thereby requires them to file Suspicious Activity Reports and comply with other AML obligations, no such rules currently apply to U.S. dealers in art.
In the 18th and 19th centuries, the mania for classification and study of the past resulted in an upsurge in forgeries as the art market adjusted to accommodate the new interest in the artistic past. That interest in the classification of the past also led to the founding of academic disciplines such as the history of art. The study of art history and the creation of agreed-upon bodies of work for artists and eras, as well as advances in science, made possible in the 20th century the winnowing out of forgeries, fakes, and misattributions from authentic works. As art historians gained more knowledge about the past and the styles, materials, and working conditions of artists and historical epochs, inauthentic and fraudulent works were more readily exposed.
