This is my "digital restoration" of the Leiden bust. Actually, this is one of two marble heads of Caesar that we can see at the page 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.
For the restoration of the face I used that of the Tusculum bust.
Actually "rectangles" are coherent (see the discussion in this post)
