The canvases by the late Kazuo Shiraga, who spread paint with the bottoms of his feet while holding onto a rope above him to keep from falling, sold at Fergus McCaffrey’s booth at the Foire Internationale d’Art Contemporain, which ended Sunday. “Ryusen” from 1991 fetched just under $4 million and “Kakueki,” a 1985 oil on canvas, went for $2.5 million.
