In the Dolphin's summer exhibition, David Ford's "USA" — a 96-inch-by-72-inch behemoth that he painted this year — was an intriguing anomaly among the more formal works. A giant black panther head exploded out of the top-left corner of the canvas, snarling yet surrounded by orange, pink and white flowers. Ford's painting may be a simplistic political metaphor (or it may not), but it's also a painting that exemplifies the self-taught Ford's iconoclastic, polyglot style.
