Artists have been copying the images and the styles of other artists for thousands of years. Up until around the 16th Century this was a common practice, used to pass down historical, religious and artistic tradition for future generations. Copying the work of others, and particularly the Masters, was a normal part of any artist's academic training. It still is, in major art schools, a normal and required part of an art student's cirriculum.
Forgeries again came into play at Turkey’s State Art and Sculpture Museum in Ankara, where a group of museum officials and criminals are believed to have teamed up to steal some 302 works from the institution between 2005 and 2009. The crime was discovered in 2012, when the museum realized that 46 pieces in the collection had been replaced by copies. Another 30 works also raised suspicion.
Finally, under Guideline 6, the AML Guidelines provides that art businesses must maintain adequate records of their due diligence efforts. Perhaps stating the obvious, but perhaps also implicitly acknowledging the existence of practices by certain dealers, the AML Guidelines observe that “[a]ll documents issued by an Art Business in connection with a transaction (e.g. valuations, sale and purchase agreements, invoices, shipping documents, import / export declarations etc.) should be true, accurate and contemporaneous and represent the honestly held professional opinions of the Art Business.” Likewise, dealers “should refuse all requests from clients to alter, back date, falsify or otherwise provide incomplete or misleading documentation or information relating to a transaction. If there are legitimate reasons for altering a document (e.g. invoicing error etc.) the circumstances and justification should be fully documented and retained on file for future reference and audit.”
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.

Tom Ripley is involved in an artwork forgery scheme in several of Patricia Highsmith's crime novels, most notably Ripley Under Ground (1970), in which he is confronted by a collector who correctly suspects that the paintings sold by Tom are forgeries. The novel was adapted to film in 2005, and the 1977 film The American Friend is also partially based on the novel.

The second essay (Purchase Price Paid Over Time: “Title Does Not Pass Until Payment in Full”) addresses a very common provision in contracts for the sale of art with installment payments. But, surprising to many art sellers, the Uniform Commercial Code probably makes this provision unenforceable, with consequences for the seller getting his art back.

The United States passed the Banking Secrecy Act in 1970, requiring financial institutions to report certain transactions to the Department of the Treasury, such as cash transactions above $10,000 or any others they deem suspicious, on a suspicious activity report (SAR). The information the banks provide to the Treasury Department is used by the Financial Crimes Enforcement Network (FinCEN), which can share it with domestic criminal investigators, international bodies or foreign financial intelligence units.
In this context, the provenance can occasionally be the detailed history of where an object has been since its creation,[26] as in art history contexts – not just since its modern finding. In some cases, such as where there is an inscription on the object, or an account of it in written materials from the same era, an object of study in archaeology or cultural anthropology may have an early provenance – a known history that predates modern research – then a provenience from its modern finding, and finally a continued provenance relating to its handling and storage or display after the modern acquisition.
The notion of intellectual property—the idea that artists’ works belong to them—dates at least to medieval Europe, though history records examples of the concept as early as ancient Greece. It had taken hold sufficiently during the Renaissance for Michelangelo to take umbrage when his work was misattributed. It was reported that when he discovered that another artist was receiving credit for sculpting the famous Pietà (now in St. Peter’s Basilica in Rome), Michelangelo returned with his chisel and added his signature across the centre of the sculpture, on the prominent sash across Mary’s upper body (in Italian): “Michelangelo Buonarroti, Florentine, made this.”
