Other aspects of documents relating to defects in features such on printed or typewritten document, the presence of trash marks or incidental marks on photocopies or laser prints etc may also yield valuable information concerning the dating of the document.
Handwriting and signatures may change with time and if reasonable volumes of comparison documentation over a period of time from the same individual can be obtained, the quality of writing or writing style may be identifiable to a particular time period.
Whilst this type of ascertainment is to the dealers advantage, for buyers it could mean the almost total loss of their investment if one day this overemphasis on the signature were considered illogical and mistaken and a more traditional way of attributing art returned to the various component materials of the painting and its support.
Any incompatibility between the measured ages and information on the presumed author reveals to the owner, before he seeks an expert opinion, that he has acquired one of the myriad recent copies in circulation.
In the past, when called on to appraise and attribute a painting, art experts examined only the surface under natural light.
A superficial examination of this kind was sufficient, however, because it was artistic style and technique they were looking fact that today, as in the future, it is often impossible to attribute a work to an author with certainty, induces the thought that current art appraisal methods are all to the advantage of the market.
The ascertainment of the authenticity of this painting has been carried out with scientific tests on the material and through the study of techniques and signs of wear.
