Object Lesson

A Calder Animobile

OBJECT Very Crinkly by Alexander Calder, signed and dated ca. 1968. At Locks Gallery in Philadelphia, Calder's hometown.

PROVENANCE Calder began making kinetic sculptures in the early 1930s. This one, from a late series that Calder's wife called the Animobiles, is 31 inches of wire and sheet metal painted in primary colors on one side and black and white on the other. The top sits on a pinhead, allowing movement; a stationary "tail" made of bent sheet metal creates the crinkled effect. Nearly all the other Crinkly pieces are in museums, making Very Crinkly, which has been in private collections since the '70s, a rare offering.

EXPERT APPRAISAL "It is a mature piece," says Locks Gallery director Sueyun Locks, "but it still has a sense of humor." The market for Calder's work, she says, is a steady one.
