These are from a great little book from 1942. It's simply titled How to draw Children, by Priscilla Pointer and is part of a series of how to art books.
I love how one of the sketches is of smiling children boxing.
This is based on a story I heard many years ago called the Seaton sailor. I like the idea that the sailor is seeing the ghost of his future self dying in the arms of his great love. The original teller thought it was simply an expression of the call the sea has on the lives of some.
