Many have been in the Eardley family since her death in 1963, and include rare paintings from her travels in Italy in the late 1940s.

Eardley, who was born in 1921, and who trained at the Glasgow School of Art, is known in particular for her portraits of street children in Glasgow's Townhead area and landscapes of the fishing village of Catterline, near Stonehaven in Aberdeenshire.

The sale has a historic significance - Eardley first exhibited at the Scottish Gallery in 1955.

Prices for the paintings and images, some in pastel and others in oil, on show and sale will range from £5,000 to £115,000.

The unseen paintings include a palazzo in Italy, an untitled sea landscape, an image of trees and haystacks, and a farm at Catterline.

At present the Scottish National Gallery of Modern Art is showing A Sense of Place, a show focussing on her paintings in Townhead and Catterline.

It shows paintings as well as sketches and photographs relating to the work of the artist who died at the age of just 42.

Christian Jansen, managing director of the Scottish Gallery, in the New Town area of the city, said: "We have been championing the work of Joan Eardley for 52 years.

"Over this time we have built up strong relationships with her family and friends who, when they want to sell, come to us first.

"We are excited to have some of her works that have not been seen in public before as well as many that are on sale for the first time ever.

"Since we announced this exhibition we have further buyers keen to have work in their possession included as well."

The show will be staged from February 1 to 25.

The Scottish Gallery is Scotland’s oldest independent gallery, established in 1842.

In 2017, The Gallery is celebrating 175 years of contemporary art.

This year it will also stage an exhibition by Geoff Uglow, a graduate of the Glasgow School of Art.

Entitled ‘The Rose Garden’, these large oil paintings are inspired by a rose garden which he cultivated over the past ten years at his home in Devon.
