A WORLD-FAMOUS £500,000 painting created in Cornwall has been given to the Tate and will be shown in St Ives in January.
The Harbour was painted by William Scott in 1952 and donated by his sons to mark the centenary of his birth.
Valued at £500,000, it has been seen from Brazil to Japan.
Scott was a traditional landscape and portrait painter through the thirties and forties, but from 1946 began spending his summers near St Ives and was closely associated with artists working in the town such as Patrick Heron (1920-99) and Peter Lanyon (1918-64).
The Harbour marked the start of a step-change in style for the artist and will be included in a centenary touring exhibition organised by Tate St Ives in association with the Hepworth gallery in Wakefield and the Ulster Museum in Belfast.
The exhibition, the first major showing of Scott's work in more than 20 years, opens at Tate St Ives on January 26.
Tate director Nicholas Serota said: "The trustees are extremely grateful to William Scott's sons for offering this significant gift to the Tate Collection on the occasion of the artist's centenary.
"This gift will transform our ability to show the radical nature of his art in the early Fifties."
Though the Tate already owns one of Scott's paintings incorporating colour – Orange, Black and White Composition, dating from 1953 – this is the first example of his seminal black and white works to be added to the collection.
Robert and James Scott, of The Scott Foundation, said in a joint statement: "We are delighted to present The Harbour to the Tate.
"It is only fitting that such an internationally known painting by William Scott now finds its home at the Tate.
"Cornwall was the very place in which The Harbour and the paintings in this group of works were first conceived."
