The 10½ x 14¾in (27 x 37cm) watercolour of a bustling street with women and children was guided at £4000-6000.
It was one of a small group of seven watercolours and drawings of various mining-related subjects by Cornish. They had been assembled by a collector from the Stone Gallery in nearby Newcastle upon Tyne, where the artist regularly exhibited in the 1960s and ‘70s.
Another highlight was a charcoal drawing of a pit pony from 1963 that tipped over top estimate to sell for £2200.
The rest got away in or below guides to total £16,850.
