Focus on Bent Propeller and analyze the Description.
The main elements of the sculpture were three sheets of curved metal, linked together to form a static work resting under its own weight, making it what Calder called a "stabile", as opposed to his famous "mobile" sculptures. It was reminiscent of a ship's propeller. Like many of Calder's public sculptures, it was painted red. The large work, 25 feet (7.6 m) high, was first installed near the entrance to WTC1 (the North Tower). It was moved in 1970 to a plaza in front of 7 World Trade Center, on the northeast corner of the Austin J. Tobin Plaza by Vesey Street and Church Street.
