LONDON .- Bidding opens this Wednesday on a group of works by the Scottish Colourists acquired by Major Ion Harrison an important patron and friend of the quartet of artists between the 1920s and 1940s. This offering of 24 works from the Harrison Collection follows Sothebys sale in June 2018 of some 30 pictures from the collection, which sold for a combined total of £4.5 million and saw a new auction record achieved for Francis Campbell Boileau Cadell. Passed down through the family, the works remained together at Croft House, Major Harrisons home where he openly welcomed the Colourists.
