My Mother stumbled across a funny little letter written to her by my Grandfather back in 1980 when I was about 3. The letter is a kindly "threat" that as the horse trainer of his race horse, she should win the coming race meet. She did not win the race, and happily G-pa did not end up selling apples and pencils on the street.
He also included some doodles at the bottom of myself and my sisters(2 at that time)
Enjoy
