IN THE PAINT: Art, they say, is subjective. Christmas day, however, is not. That means you've got a couple days to get to The Wolfsonian gift shop, where they've got signed copies of "Painting Below Zero," a biography about pop artist James Rosenquist. The lucky, culture-hungry recipient will learn about how Rosenquist grew up in North Dakota with a bunch of Scandanavian farmers and spent nights in NYC's Cedar Tavern shooting the shiz with Willem de Kooning. Ah, nothing says the holidays like a reminder of your own life's lameness. GET IT: $50. The Wolfsonian, 1001 Washington Ave., Miami Beach; 305-535-2680.
