This is my "digital restoration" (on the right) of the Leiden bust of Caesar (on the left). 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)
