A monumental sculptural forgery was a copy based on a Greek bronze statuette of a warrior of 470 bc, only five inches high and located in the Antikenabteilung, Berlin. The forgers made an eight-foot-high reproduction of it in terra-cotta and offered it as an Etruscan masterpiece. The resemblance was noted by the experts, who thought it to be an example of an Etruscan artist borrowing a Greek design motif. In 1961, after it had been in the Metropolitan Museum of Art in New York for 40 years, an analysis was made of the black glaze that covered the figure. It was found that the glaze contained as a colouring agent manganese, which never was used for this purpose in ancient times. Finally, Alfredo Adolfo Fioravanti confessed that he was the sole survivor of the three forgers.
Also the documents supposedly supporting the authenticity of the art were forged. According to the art fraud detective, the fraudulent art pieces looked like they had been purchased in a dollar store because they were so bad. When the police searched his one-room condo, some of the works still were wet with paint. At the time of his arrest, another buyer filed a complaint that the piece she purchased from him was a forgery (Moore, 2004).
Of the 10 civil lawsuits brought against Ann Freedman and Knoedler Gallery, six have been settled out of court for undisclosed sums, including Domenico de Sole's case, over that fake Mark Rothko. As for Ann Freedman, she is back in the art business. She has opened another gallery and is once again selling paintings just a few doors down from her old gallery in New York City.
At times restoration of a piece is so extensive that the original is essentially replaced when new materials are used to supplement older ones. An art restorer may also add or remove details on a painting, in an attempt to make the painting more saleable on the contemporary art market. This, however, is not a modern phenomenon - historical painters often "retouched" other artist's works by repainting some of the background or details.
A forgery ring busted in 2011 is still having repercussions across the Alberto Giacometti market. Dutch Giacometti forger Robert Driessen made €8 million ($8.9 million) selling forged sculptures, along with thousands of fake bronzes, before his misdeeds were discovered. In 2015, the case again made headlines when a German dealer was caught trying to sell one of the works still at large to an undercover agent.
It is hard to imagine a business more custom-made for money laundering, with million-dollar sales conducted in secrecy and with virtually no oversight. What this means in practical terms is that “you can have a transaction where the seller is listed as ‘private collection’ and the buyer is listed as ‘private collection,’ ” said Sharon Cohen Levin, chief of the asset forfeiture unit of the United States attorney’s office in Manhattan. “In any other business, no one would be able to get away with this.”
Well, they are. In 2014, Texas business man Phillip Rivkin was charged with 68 counts of fraud after using millions of dollars worth of photographs to launder money. He had made over $78 million through fraudulent schemes involving his biodiesel production companies—which didn’t actually produce any biodiesel. Rivkin spent roughly $16 million dollars on 2,200 fine art photographs by artists like Edward Steichen, Alfred Stieglitz, and Edward Weston. Works included Edward Weston’s Dunes, Oceano, a gelatin silver print that Rivkin purchased from Sotheby’s for $134,500 and another vintage gelatin silver contact print by Alfred Stieglitz, From the Shelton, West. Rivkin wired Camera Lucida, the seller of the photograph, $150,000 to purchase it.
Governments around the world have stepped up their efforts to combat money laundering in recent decades, with regulations that require financial institutions to put systems in place to detect and report suspicious activity. The amount of money involved is substantial: According to a 2018 survey from PwC, global money laundering transactions account for roughly $1 trillion to $2 trillion annually, or some 2% to 5% of global GDP .

Portrait of a Woman, attributed to Goya (1746-1828). X-ray images taken of this painting in 1954 revealed a portrait of another woman, circa 1790, beneath the surface. X-ray diffraction analysis revealed the presence of zinc white paint, invented after Goya's death. Further analysis revealed that the surface paint was modern and had been applied so as not to obscure the craquelure of the original. After analysis, the conservators left the work as you see it above, with portions of old and new visible, to illustrate the intricacies of art forgery, and the inherent difficulty of detecting it.
Within computer science, informatics uses the term "provenance" to mean the lineage of data, as per data provenance, with research in the last decade extending the conceptual model of causality and relation to include processes that act on data and agents that are responsible for those processes. See, for example, the proceedings of the International Provenance Annotation Workshop (IPAW) and Theory and Practice of Provenance (TaPP). Semantic web standards bodies, including the World Wide Web Consortium in 2014, have ratified a standard data model for provenance representation known as PROV which draws from many of the better-known provenance representation systems that preceded it, such as the Proof Markup Language and the Open Provenance Model.
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.
