The artist is David Lance Goines. Many of us here own DLG posters already. If you’ve circulated and in the S.F. Bay Area for 30 years or so and have paid attention to nice-looking-things-on-walls, generally framed, you’ve seen his work. And if not, you can see it here: http://www.goines.net/poster_art.html
It's of Milo, son of our own former employee Keven and his wife, Dynelle.
