Clothespin (Philadelphia) (B. Krist for GPTMC)

Ask for directions in Philadelphia and you're likely to hear: "Turn left at the clothespin." Claes Oldenburg's Clothespin, a rusty 45-foot steel sculpture hovering over Centre Square Plaza at 15th and Market, stands in stark contrast to the ornate City Hall across the street. The Clothespin was Oldenburg's first permanent monument in the Unites States. Built in 1976 from 10 tons of stainless steel and Cor-ten, the sculpture is actually two separate structures held together by a tension spring, much like a real clothespin. This imposing ode to laundry at the center of Philadelphia's business district was used to full ironic effect in the film "Trading Places." -- Cathleen McCarthy
