Alexander Calder Untitled (The Constellation Mobile)

This free-floating sculpture, called a mobile, hangs from a wall or the ceiling. At the top, four wires curve upward in a spray, two to each side. Below, six wires bow in descending branch-like forms. Eleven small shapes, each in the form of a ball, comma, hourglass-like shape, or paddle, is affixed to or hangs from the end of each wire, and each is a single color in black, yellow, or red.
