Trees by Karl Weschke, 1970, oil on canvas, 4ft 11in x 4ft (1.52 x 1.22m).
Running from April 8 to May 8 the show includes works by Wilhelmina Barns-Graham, Dennis Creffield, Barbara Hepworth and Ben Nicholson among others.
The Weschke picture represents the stylistic break from his earlier abstract style which took place when he moved to Cornwall in 1955.
He began to create haunting, figurative landscapes such as Trees, which was likely inspired by the moors and stunted trees near his home as well as his experience as a prisoner of war. The picture is offered for £6800.
Homage to Constable, 1976 by John Hoyland, lithograph with acrylic hand working, 22in x 2ft 9in (55 x 85cm).
Belgrave St Ives moved from town to countryside in 2022. The new location is near Towednack, which has been home to artists such as Weschke, Trevor Bell and Roger Hilton.
