The Child is the Father of the Man

Oh, wait. The man is the father of the child. No, the child is the man, and the father is the father. But the father is a son

A prize to the person who can figure out this riddle.

Okay, I'll tell you. The figures on the left are my son and his son, maybe 15 years ago. The figures on the right are the same son and his son, today--which happens to be my grandson's 19th birthday and a fit occasion for recreating the original photo.
