Posthumous casts made from an artist’s lifetime models represent a complex issue for art historians, museums, art foundations, auction houses, curators, collectors, conservators, art lawyers and the art market. The question of how to evaluate and write about these casts is also of vital importance for those working on catalogues raisonnés. The intent of this conference is to share different concerns and viewpoints as well as to come up with new ideas about how to exhibit, label and designate posthumous casts within an artist’s oeuvre.
