This untitled watercolour above from 1989 is by Maurice Estève (French 1904-2001), one of its foremost representatives of the non-representational art movement known as Tachisme.
A relatively later work dated 1989, it carries an estimate of £8000-12,000 at Lots Road Auctions in London on January 26.
A collection of African tribal art will be offered by Anderson & Garland in Newcastle upon Tyne on January 24.
The group forms part of a much larger assemblage, the bulk of which was sold in Paris by a Belgian collector who was posted to the Congo in the 1950s through to the mid-1960s. This tranche, in storage for years in an outhouse, belonged to a family member who had got as far as taking it to a car boot fair for sale. Deluged by requests for prices, he was advised by a friend to put the pieces back into the car, return home and then seek the advice of an auction house.
Among the financial highlights of the collection is a 4ft (1.31m) red, white, blue and black Kifwebe shield from the Songye people of Democratic Republic of the Congo.
