Art forgery is the practice of creating or altering artworks to deceive buyers into believing they are genuine pieces by famous artists. Forgers often replicate the style, techniques, and materials used by renowned creators, such as Vincent van Gogh or Pablo Picasso, to make their fakes more convincing. This illegal activity can undermine the art market and diminish the value of authentic works. The consequences of art forgery can be severe, leading to legal action against the forgers and financial losses for collectors and galleries. Institutions like museums and auction houses invest in authentication processes to protect against forgeries, employing experts and scientific methods to verify the origins and authenticity of artworks.
