Jack Flam took his information to the FBI's Art Crimes unit, which launched an investigation. In 2013, Glafira Rosales confessed to playing a key role in the multimillion dollar fraud. She is now awaiting sentencing, and told the FBI the forgeries were the handiwork of this man: Pei-Shen Qian, an artist who lived in Queens and painted the works in his garage.
Excluded from the category of literary forgeries is the copy made in good faith for purposes of study. In the matter of autographs, manuscripts in the handwriting of their authors, forgeries must be distinguished from facsimiles, copies made by lithography or other reproductive processes. Some early editions of Lord Byron’s work, for example, contained a facsimile of an autograph letter of the poet. If such facsimiles are detached from the volumes that they were intended to illustrate, they may deceive the unwary.
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.
Eli Sakhia was a respectable art gallery owner in business for 15 years in Manhattan. He sold privately and to auction houses in the United States and abroad. What he failed to tell his private buyers was that they were buying the forgeries and the auction houses were getting the real works. His modus operandi was to purchase originals, sell them to auction houses, and hire artists in the interim to reproduce fakes for sale to his clients. His problems started when a past buyer of a fake tried to sell his forged piece while Sakhia attempted to sell the original to another auction house. The houses brought in an expert who stated that the past buyer's work was a fake. Sakhia was arrested and convicted; he's expected to serve three to four years in prison (Campanile, 2004).
Art Businesses should also consider the form of the transaction, such as whether the transaction is taking place through intermediaries, face to face, entirely via the Internet, over the phone, or by any other similar non face to face means. In some circumstances, depending on the nature, value and/or geographic location of the transaction, enhanced due diligence may be appropriate.
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.

A tale of literary forgery that came to light in the early 21st century was that of the celebrity biographer Lee Israel, who confessed in her memoir, Can You Ever Forgive Me? (2008), that while down on her luck in the 1990s she had forged and sold to collectors hundreds of letters by various notable figures—Louise Brooks, Noël Coward, Dorothy Parker, Humphrey Bogart, and Lillian Hellman among them.
— The United Nations Office on Drugs and Crime estimates the amount of illicit money that is laundered each year to be between “2 - 5% of global GDP, or $800 billion - $2 trillion in current US dollars.” The difficulty of knowing exact figures accounts for the huge margin within estimates. The UN’s estimates specifically cite “Mega-Byte” as an issue, defining the term as “money in the form of symbols on computer screens the can move anywhere in the world with speed and ease.”

Forgeries may be detected by the methods of examination formulated by Jean Mabillon, in his great work De re diplomatica (1681), for determining the authenticity of a document by the writing and the style of the terminology. These techniques have developed during three centuries into the modern sciences of paleography and diplomatics, by which various scripts and formulas can be assigned to particular ages and localities, and effective comparison can be made between two examples of handwriting purporting to come from the same pen. Thus it is possible to state that a particular document could not have been written at the date that it bears. In dealing with printed texts, analogous methods are employed.

There are several maintained and open-source provenance capture implementation at the operating system level such as CamFlow,[42][43], Progger[44] for Linux and MS Windows, and SPADE for Linux, MS Windows, and MacOS.[45] Other implementations exist for specific programming and scripting languages, such as RDataTracker[46] for R, and NoWorkflow[47] for Python.

In summer 2009, ARCA - the Association for Research into Crimes against Art - began offering the first postgraduate program dedicated to the study of art crime. The Postgraduate Certificate Program in Art Crime and Cultural Heritage Protection includes coursework that discusses art fakes and forgery. Education on art crime also requires research efforts from the scholarly community through analysis on fake and forged artworks.[32]
* An illustration of the art taken from an old auction catalog without the accompanying description does not constitute valid provenance unless the auction house is or was able to demonstrate beyond doubt that the art was by the artist in question. For example, the auction house may have sold it as "attributed" to the artist. Again, get a copy of the actual auction catalog or read the full listing online to see how the art was described and represented.

Despite all the studies and technical tests available, forgeries will still be made. The 20th-century art forger is far better equipped and much more knowledgeable than his predecessor. The demand for rare works of art has increased, and he will attempt to supply them. In collecting, whether by the private collector or by a museum, there comes a point when, after all the studies and all the tests are conducted, a decision has to be made as to whether or not to purchase a piece in question. The element of risk can be minimized but not eliminated. At this point, the collector should be ready to back his opinion with the purchase price. In order to acquire great pieces, particularly from newly discovered and relatively unknown cultures, it is necessary to take a calculated chance. The collector who has never bought a forgery probably has never bought a great piece of art.

Fakes and forgeries in the art world are the stuff of legend, the subject of books, films, and television series the world over. In real life, they land people behind bars. 2016 brought us many unwanted things, but it also appears to have been a year when a huge amount of authenticity disputes took place. The spats took shape from contested provenance, to painters faking their own work, to a multimillion dollar Old Masters scandal. From farce to tragedy, we’ve compiled the highlights of this year’s biggest art forgery scandals below.

A variation in composite forgery, quite common with inlaid French furniture, involves the use of parts from damaged but genuine pieces to create a single complete piece that may or may not resemble one of the pieces from which it has been made. These made-up pieces are still considered forgeries. In composites of archaeological material only one part may be ancient, the balance being made up to complete the object. The head of a small terra-cotta figure may be ancient, the body and limbs of modern workmanship. A single ancient element in a composite forgery will help to deceive the buyer.
In the early 2000s, Brazilian financier Edmar Cid Ferreira had embezzled funds from his business empire — and he needed a way to hide the money. He found it in Hannibal, a painting by American artist Jean-Michel Basquiat. Appraised by the art world at $8 million, Ferreira showed up at New York’s Kennedy Airport in 2007 with the painting and a bill of lading listing the value as $100.
Any given antiquity may have both a provenience (where it was found) and a provenance (where it has been since it was found). A summary of the distinction is that "provenience is a fixed point, while provenance can be considered an itinerary that an object follows as it moves from hand to hand."[25] Another metaphor is that provenience is an artifact's "birthplace", while provenance is its "résumé",[26] though this is imprecise (many artifacts originated as trade goods created in one region but were used and finally deposited in another).
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.
