ONE of the finest Lowry paintings, depicting Liverpool's waterfront, could sell for £500,000 when it goes under the hammer at auction.
The re-discovered masterpiece, titled Liver Building, Liverpool, has caused excitement among experts at auction house Christie's who have described the image as iconic.
It has been in a private collection for more than 40 years, and has only been seen in public once, at the Walker Art Gallery in 1973.
Since then it has remained in the collection of the late Robert Sangster, one of the most renowned figures in the world of horse racing and the son of Vernon Sangster, founder of the Vernons Pools business.
Two other works by Lowry from the Sangster collection, including a painting from 1935, will also be sold in London on June 9 during British Art Week.
A spokesman for Christie's said: "Lowry's style saw him portray the townscapes created by the industrial revolution, often showing skylines of smoking chimneys and streets teeming with people.
"These landscapes were often composite images created partly in his imagination but The Liver Building, Liverpool, which was painted in 1962, steps away from this trend and offers a faithful view across the Mersey to the distinctive skyline.
