At Art Basel Miami this year, artists William Powhida and Jennifer Dalton whittled up a few dirt cheap six-piece box sets of Leunig-like condolence cards throwing those words that every artist (except maybe Jeff Koons) has probably heard once or twice: “I Am So Sorry for Your Loss of Representation … But please take me off your mailing list.” And, here, the street sign for West 24th Street: "All Good Things Must Come to an End.” We’re hoping the sweet price — $150 a box — reflects the sort of recession prices to come.
