Here’s the mural plan laid out on a table at La Colombe the excellent coffee house on Main St. around the corner from the mural. See the picture bigger here.
The artist’s design shows a sublime landscape of rocks, sea and sky with figures symbolizing cancer survivors dancing in the sunset.
The landscape depicted is the Headlands, a part of the San Francisco Bay area (Sausalito, maybe) where Northrup grew up. Last summer she did an artist’s residency at the Headlands and this mural’s vista is from the photographs she took.
