Father and Son - 2

In July 2010 showed an image of a sculpture I saw in Tartu, Estonia in August 2008. I also said that I was well acquainted with scientific diagrams which scale infants and adults to the same height (in order to demonstrate how body proportions change with age). This is a less frequently found image. It again scales adult and child to the same height but this time internal structure are also seen. Note how they are not in the same proportions.
