It's nice to have some memories of your mother and it was a nice gesture to restore one and send it to your sister.
My dad was an artist, passed away last year, and all of us, his five children, have some of his artwork hanging in our homes. It's a nice way to feel a little closer to him and remember the good times. Thanks for sharing.
I'm sorry to hear about your Dad. That is a very personal and wonderful way to remember him, by his art.
