The Ellen Harvey Exhibit at the P3 Studio in the Cosmopolitan Monday, Dec. 17, 2012. "Exchange Your Luck" allows guests to swap ineffective lucky charms for new ones. Two adjacent shelves in P3Studio will hold two sets of 77 different small bronze lucky charms by Ellen Harvey. Each charm will be an edition of only two. One set of charms will stay in P3Studio for the duration of the residency, while the other set is available for guests to take provided they leave their own lucky charm in exchange. The object for which the charm is swapped will be photographed and its Polaroid installed on the wall.
