Lynn Chadwick's Two Winged Figures made $43,750 at Swann Auction Galleries' Contemporary Art sale in New York on May 13.
The patinated bronze pair were valued at $9,000, resulting in an increase of 386.1%.
Both are artist's proofs, typical of the elegant and organic metal sculptures that Chadwick began producing in the 1940s. Each was produced in an edition of 10 and stands at just under eight inches tall.
During the 1950s and 1960s, Chadwick was among the most famous sculptors in the world but fell out of favour with the advent of pop art.
His auction record stands at a comparitively low $2.6m - set for Couple on Seat in 2006.
 Lynn Chadwick's market is undergoing something of a renaissance |
However, it appears that his market is now primed for reinvigoration - in part due to the roaring success of similar artists like Alberto Giacometti and the fact that this year marks 100 years since his birth.
Adrian Sutton, director of Blain/Southern - a major gallery that now represents Chadwick's estate, told Artnet: "I think it's fair to say that he was forgotten.
"His career didn't go in the same way as Giacometti's, but that's what we are trying to readdress."
Roy Lichtenstein's Crying Girl was another highlight, achieving $37,500 against a $30,000 estimate - an increase of 25%.
The colour lithograph is signed in pencil by the artist and is one of many images of vulnerable women that he produced during the early 1960s, at a time when his marriage was beginning to fall apart.
