One of the earliest examples of David Smith’s welding is shown for the first time in this exhibition of more than 30 works drawn from the BMA’s collection, the Estate of David Smith, and private collections. Once considered “lost” by the Smith Estate, Head with Cogs for Eyes came to the BMA last year as part of a generous bequest. It is joined by works by Hans Arp, Naum Gabo, Julio Gonzalez, Henry Moore, Louise Nevelson, and other modern artists who moved beyond the figure to create sculptures based on a new language of abstract forms.
