Information, documentation and certification in western and ethnic art

The study of a cognitive and experimental nature regards the sector of ethnic artifacts, especially interesting from a socio-historical point of view as well as a technical-conservative one, but at the same time the object of limited research. In the present paper the specific area of knowledge of the art market is present, in relation to the various economic-financial and diagnostic-analytical-material aspects. The consequent result, that derives from the meeting point of the different scientific competences and experiences can supply an initial and nonetheless significant contribution for a complete and correct evaluation in the sector of ethnic products.
