I think that's a splendid offer for your friend's Dad. He could use it to showcase his art. Just because he's retired doesn't mean he's dead and not wanting to sell or show off his talents. Give that a go. And you'll have that person you can sit down with and you have an idea what you want it to look like.

If you need it for print, you'll need "camera ready" art. You can scan it into photoshop and save it as a scalable eps file.
