The Dutch forger Han van Meegeren employed a combined composite and stylistic procedure when he created seven paintings between 1936 and 1942 based on the work of Johannes Vermeer. In The Supper at Emmaus he combined figures, heads, hands, plates, and a wine jar from various early genuine Vermeers; it was hailed as a masterpiece and the earliest known Vermeer. Ironically, van Meegeren never was detected as a forger. At the end of World War II he was arrested for having sold a painting attributed to Vermeer to one of the enemy and was accused of being a collaborator. He chose to reveal himself as a forger, which was a lesser offense, and proved his confession by painting another “Vermeer” under the eye of the authorities.
Statistical analysis of digital images of paintings is a new method that has recently been used to detect forgeries. Using a technique called wavelet decomposition, a picture is broken down into a collection of more basic images called sub-bands. These sub-bands are analyzed to determine textures, assigning a frequency to each sub-band. The broad strokes of a surface such as a blue sky would show up as mostly low frequency sub-bands whereas the fine strokes in blades of grass would produce high-frequency sub-bands. A group of 13 drawings attributed to Pieter Brueghel the Elder was tested using the wavelet decomposition method. Five of the drawings were known to be imitations. The analysis was able to correctly identify the five forged paintings. The method was also used on the painting Virgin and Child with Saints, created in the studios of Pietro Perugino. Historians have long suspected that Perugino painted only a portion of the work. The wavelet decomposition method indicated that at least four different artists had worked on the painting.
On the night of St Patrick's Day in 1990 when the attention of Boston was focused elsewhere, thieves entered the Isabella Stewart Gardner Museum and made off with art valued at $500 million, including three Rembrandts, one of only 34 known paintings by Vermeer, and works by Manet and Degas. Because the eccentric Isabella insisted in her will that nothing be changed in the museum (nothing!), the empty frames remain on the walls as a sad reminder of what has been lost.
Redistribution of the world’s wealth after the Renaissance created an explosive demand for art by a newly educated and prosperous mercantile middle class. Guilds of Master artists and students became virtual factories for art that was produced to fill this demand. The sale of State and Ecclesiastical art collections created new secondary markets in the form of dealers, galleries and auction houses. For the first time in history, art became a commercial commodity.
The Responsible Art Market, or RAM, is an industry-supported not-for-profit organization which describes itself as ‘”[r]aising awareness of risks faced by the art industry and providing practical guidance on establishing and implementing responsible practices to address those risks.” On its website, RAM provides both an Art Transaction Due Diligence Toolkit, as well as Guidelines on Combatting Money Laundering and Terrorist Financing (“AML Guidelines”). The AML Guidelines are similar to the protocols set forth by the Basel Institute, but provide slightly more concrete detail. They set forth eight basic principles:

The copying of famous works of art dates to the origins of the history of art collecting and therefore to the beginning of the history of art. In the ancient world, replicas of famous works were made in order to satisfy demand by collectors for such works. The bronze Spear Bearer (c. 450–440 bce) by Greek sculptor Polyclitus, for example, achieved great renown for its perfect proportions and beauty. As a result, it was often copied in marble for Roman collectors in subsequent centuries. The copies, which are all that survived into the 21st century, made no pretense of being the original or having been made by Polyclitus.
