Cedric Morris's The Red Pond (1932). The Barbara Holliday Collection of 20th-Century Modern British paintings and sculpture, Sworders Fine Art Auctioneers, Stansted Mountfitchet, UK, 15 January. Estimate £15,000-£25,000: In the 1960s, from her home in Cumbria, Barbara Holliday started to collect Modern British art, initially inspired by her friendship with the local artist Sheila Fell. Over the next 50 years, Holliday amassed a vast collection, buying from artist friends such as Olwyn Bowey, Carel Weight, Eduardo Paolozzi and numerous Royal Academicians. Holliday’s 440-lot collection is expected to make up to £400,000 at Sworders and a highlight is this rather sinister painting by Cedric Morris (best known as Lucian Freud’s tutor), which was once owned by the artist Maggi Hambling.
