Digital restoration of one of the two marble heads of Caesar at http://www.rmo.nl/onderwijs/museumkennis/klassieke-wereld/romeinen/de-voorwerpen/julius-caesar
The Rijksmuseum van Oudheden is the national archaeological museum of the Netherlands. It is located in Leiden. On the left, I used the face of the Chiaramonti Caesar, on the right the face used is that of the Tusculum bust.
