ARTWORK by Stroud sculptor Lynn Chadwick fetched £446,500 when it was auctioned on Wednesday.
Two Reclining Figures by Lynn Chadwick was expected to attract bids of between £400,000 and £600,000 by London auction house Bonhams.
It was the top seller at the Bond Street auction of British and Irish modern art, which sold just over £3.5million-worth of lots in an afternoon.
Preparations are also under way to celebrate the 1914 birth of the sculptor who lived most of his life at Lypiatt Park until his death in 2003.
Gallery Pangolin in Chalford will unveil a special exhibition including a recreation of his studio, at Stroud Museum in the Park from June 14 to July 13.
