This 21-work survey of mostly carved wood sculpture supplies another chunk in the history of postwar American art. Influenced by folk art and trained for a year by a shipbuilder, Ms. Kruger developed her art sculpture by cutting woodblocks for prints, as an enormous example here attests. Her life-size figures, portrait busts and political asides are in step with other artists of her generation, including Bill King and Marisol. But her works have their own formal quirks, telling abbreviations, lustrous finishes and quiet, watchful force.
