“The Irreverent Art of Skip Williamson” at Vinson Gallery on Decatur Square must be the most accurately labeled art show of the month. Any show that features “Last Call,” a painting of a downcast Jesus surrounded by empty Rolling Rock bottles in a bar, wins the irreverence sweepstakes.

But Williamson’s irreverence is equal-opportunity. While art director of Playboy magazine, he produced a 1980 cartoon, “Hugh Hefner as an Infant.” An adult-faced baby Hefner stares at the breasts being pushed in his face and thinks, “Good!”

And often Williamson skewers politics without taking the side of one party or another; his two-faced politicians “Inside the Beltway” have no party labels.

And his hip-looking homeless man with a “will leave you alone for food” sign isn’t entirely a party-line piece of art, either.

The show’s oldest work is “PigPen,” a 1967 woodcut of the Grateful Dead musician. Some of the newest works deal directly with his years in Atlanta.

So this is a whole generation’s worth of outrageousness, and Vinson Gallery has used its down-the-hall location to present controversy that is in-your-face only after you bring your face into the gallery.

Many of you should make that effort. You know who you are.
