Alexandre Arrechea, No Limits

A new city-within-a-city has sprung up along the Park Avenue Mall: the latest public-art show conceived by the Fund for Park Avenue’s Sculpture Committee. Cuban-born artist Alexandre Arrechea, 42, put up the steel sculptures that create a walkable art tour between 54th and 67th Sts. Each piece is a riff on an iconic NYC building that twists and bends its source of inspiration as though it were a malleable garden hose. Among the architectural gems depicted are the Empire State and Chrysler buildings, plus lesser-known edifices such as the Helmsley, Seagram and Citigroup buildings.—Lee Magill
