PrintBasel standards definitely lay down that only original prints are to be shown. All prints must be framed. As far as buyers are concerned, each exhibitor must guarantee the authenticity, the authorship and the right title of all works of art shown. Each print shown must be labeled in a way that describes it accurately, completely and correctly (i.e. title, name of the artist, date/year, no/edition, technique, printer, price, literature, exhibitions, etc.). Prints made posthumously, or under other restrictions, are to be labeled as such.
