The laws of supply and demand dictate that there will be no end to the growing commercial value for a limited number of great works of art; and as long as those who deal in the commercial aspects of art — galleries, art dealers, auction houses and the media — are involved as the arbiters of criteria in judging art, market prices will continue to rise and art forgery will proliferate.
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).
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.
There are many forms of provenance documentation. A signed statement of authenticity from the artist or an expert on the artist is ideal. An original gallery sales receipt, receipt directly from the artist, or an appraisal from an expert in the era are also good options. Unfortunately, anything can be copied or falsified, but these are generally good options.
In order to fool inexperienced buyers, unscrupulous sellers often say they have provenance or documented ownership histories that they claim confirms the authenticity of bogus art. In some cases, this concocted provenance appears to date all the way back to the original artists themselves. Before bidding on or buying any art, your job is to make sure any such provenance offered by sellers is correct, legitimate, verifiable and does in fact attest to the authorship of the art. (Problem art may also be accompanied by questionable Certificates of Authenticity. To evaluate a Certificate of Authenticity or COA, read Is Your Certificate of Authenticity Worth the Paper It's Printed On?)
Sometimes provenance can be as simple as a photograph of the item with its original owner. Simple yet definitive documentation such as that can increase its value by an order of magnitude, but only if the owner was of high renown. Many items that were sold at auction have gone far past their estimates because of a photograph showing that item with a famous person. Some examples include antiques owned by politicians, musicians, artists, actors, etc.
Another area of art fraud motivated by the demands of the art market involves the smuggling of works of art out of countries, especially from developing countries, where the value of the work may be poorly understood. Though smuggling is in itself a crime, art fraud may also occur when the smugglers minimize the value of the art to guardians of cultural patrimony or to customs officials. Goods thus transported are often offered elsewhere for high prices. There are sanctions against museums that buy artworks obtained in that manner, but governments of the originating country have little recourse when the objects disappear into private collections.
