From miniature maquettes, works on paper and jewelry to monumental sculptures and one of the artist's largest mobiles, this exhibition offers viewers a sense of the range of Alexander Calder's work from 1927 through the mid-1970s. More than forty original works of artâmany of them from Jon and Mary Shirley's extensive collection, which is rarely seen by the publicâtrace the development and amazing creativity of the American master sculptor, with particular depth in his most celebrated period, the late 1940s. Alexander Calder: A Balancing Act is complemented by a related exhibition of photographs showing the artist at work, organized with the help of the Calder Foundation.
