The Facts
On August 26, 2026, Christie's announced that Piet Mondrian's 'Composition III' (1920) will be a highlight of its 20th/21st Century: London Evening Sale on October 14, 2026, during Frieze Week. The work carries an estimate of £20,000,000-30,000,000 and is the most important Mondrian offered at auction in Europe since 2009. It comes to auction for the first time, with past custodians including architect Armand P. Bartos and his wife Celeste. Painted in 1920, the work dates to a pivotal moment when Mondrian achieved the first breakthroughs of his Neo-Plastic style; only eight such paintings were completed that year, five of which are held in museum collections including Tate, MoMA, and the Stedelijk Museum.
The Signal
The consignment of 'Composition III' represents a rare opportunity for collectors to acquire a museum-quality Mondrian from his defining year, a period when the artist systematically established the principles of his abstract language. The estimate reflects the work's art-historical significance and the strong market for blue-chip Modernist works, particularly those with pristine provenance and first-time auction appearances. For collectors, this sale signals a potential benchmark for Mondrian's market in Europe, following the record prices achieved for his works in recent years at major auction houses.
