Have you seen this painting?

Have you seen this painting? Looking for its current owner to find out if it can be borrowed for a huge retrospective show featuring the best artists from the last many years of DC's storied art history.

It's called "Last Washington Painting" by Alan Sonneman. A collector named Marc Moyens originally owned it but later sold it, and there is no record of who bought it from him.

Email me HERE if you have any clues as to its whereabouts. Thanks!
