moreover, in the most of the time I work with the courts who appeal to me during litigation concerning works of art or works of art quite simply especially to carry out a technical analysis, scientific analysis on the authenticity of art , on its origin.i often help the judge to have more knowledge on the work of art and on the way in which he will have to apprehend it but also I intervene as witnesses after having studied and analyze the art to certify or not the creation of the work of art by such or such author.
