Clothespin is a weathering steel sculpture by Claes Oldenburg, located at Centre Square, 1500 Market Street, Philadelphia. It is designed to appear as a monumental black clothespin. Oldenburg is noted for his attempts to democratize art with large stylized sculptures of everyday objects, and the location of Clothespin, above Philadelphia’s City Hall subway station, allows thousands of commuters to view it on a daily basis. It was commissioned in May 1974 by developer Jack Wolgin, as part of the Philadelphia Redevelopment Authority’s percent for art program, and was dedicated June 25, 1976.[4][5]
Made of Cor-Ten steel, Clothespin is praised by art critics for its velvety texture and weathered, warm reddish-brown color.The silvery steel "spring" part of the two-textured work resembles the numerals "76", apt for the United States Bicentennial year. Tying in Philadelphia’s colonial heritage with its difficult present, Clothespin addresses the city’s civic issues and tries to bridge gaps across income levels through its universally recognized form.
