A thirty-nine-foot banner was unfurled in the rotunda of a sparsely-attended Guggenheim Museum this evening, the latest action carried out by the Gulf Ultra Luxury Front (G.U.L.F.) activist group. Decrying labor abuse at the museum’s planned Abu Dhabi outpost, the banner announced the forthcoming “Countdown” campaign by Gulf Labor, the larger collective of artists and activists of which G.U.L.F. is an offshoot.
