Dame Barbara Hepworth's (1903-1975) Figure in a Landscape (Zennor) will auction with a £90,000 ($140,319) estimate at Sworders Fine Art Auctioneers on September 9.
It is one of the largest fine art sales ever held at the auction house, reports the Saffron Walden Reporter.
The small sculpture is cast from bronze and stands on a wooden plinth, and is named for the Cornish hamlet of Zennor that provided the inspiration for the piece.
John Black, the auction house's director, told the publication: "This bronze is a very significant piece and is one of only seven ever cast. Her iconic work made a significant contribution to post-war modernism and is becoming increasingly sought after."
Hepworth is among the most celebrated British sculptors and certainly the best known of the St. Ives school, a collective of artists that lived and worked in the small Cornish fishing village of the same name.
Her work is characterised by organic, abstract forms, many of which are large scale outdoor pieces.
Hepworth regularly commands five figure price tags. In July of this year a sculpture titled Curved Form (Bryher II) sold for a Hepworth record of $3.6m, almost doubling the previous highest price paid of $2.2m.
The auction features over 800 lots, including a number of art deco pieces by Frank Dobson - a Dobson bronze bust is expected to exceed its estimate of £5,000 ($7,816).
A number of highly collectible pieces by the ceramic artist Clarice Cliff will also feature.
