The Unknown Artist:
Davies is something of a recluse, not given to answering emails and talking on social media. If you want to see more of his work then why not go over here
There's a contact page on there and they will relay any messages you have for him, as long as they are of a polite nature.
There are also loads of prints of his work there. So go and buy some, put a rare smile on his face. Please.
