A forged painting is a work of art that has been created to imitate the style of a famous artist, often with the intent to deceive collectors or institutions. These forgeries can be made using similar materials and techniques to those used by the original artist, making them difficult to distinguish from authentic pieces. The practice of forging paintings has a long history, with notable cases involving artists like Han van Meegeren and Elmyr de Hory. Art experts and institutions often employ various methods, such as scientific analysis and provenance research, to identify and authenticate genuine works of art.
