The Painting's (not) In The Mail

Until recently, the only good thing about the Castro Valley Post Office was a painting that hung on the wall to the left of the service windows. It was a low-key piece of artwork; you may not have even noticed it. It depicted an old-fashioned mail delivery Jeep parked in an empty parking lot. The painting (artist unknown) was a welcome patch of hand-wrought humanity in a sea of government-issued posters and advertisements.

Now, however, the painting has been removed, along with all other signs and printed materials. One hopes that they've been taken down so that the office can be painted, and that the painting will be returned to its rightful place once the work is completed.

Does anybody know what the story is behind the painting, and behind its removal?
