The skeleton as a basis for reconstruction. In this project, Self-portrait 21, the 3D copy of the skull represents the true image (vera icon). This image has formed the basis for a facial reconstruction by a forensic anthropologist, who received the skull anonymously accompanied only by the information that it belonged to a man in his mid-40s born in Western Europe. This facial reconstruction is based on the available scientific documentation of tissue structure, skin thickness and muscle groups. The clay reconstruction has been cast in bronze to be presented as Self-portrait 21, a self-portrait that has not been made by the artist.
