Recently presented for auction at Chrisitie's was the work of Alexander Calder (1898-1976) called "Red Curlicue." The piece is made of stabile-painted sheet metal, 192 x 126 x 96 inches. It was executed in 1973.
From the New York Times:
“Red Curlicue” signed with Alexander Calder’s initials “CA” is made of sheet metal painted a bright red. The monumental stabile, as the Paris-based American artist called those of his works that were set on the ground and did not sway in the wind, is 192 inches, or about 488 centimeters, high. Executed in 1973, “Red Curlicue” brought $6.35 million. It too has a tongue-in-cheek touch, conveyed by the curling movement of a tapering metallic sheet, which calls to mind cutouts made by children amusing themselves with paper and scissors.
