Guided by exceptional connoisseurship and a shared vision, Roger and Josette Vanthournout are responsible for one of Europe’s most discerning private collections.
Meticulously assembled over six decades and spanning nearly 150 years of artistic innovation, the works reflect the intellectual curiosity and passion of its founders, alongside Belgium’s outward-looking cultural traditions. From Surrealism and Dadaism through to key strands of Post-War avant-garde, the collection encompasses the breadth and depth of modern artistry. Highlights range from Belgian masters such as René Magritte and Gustave de Smet to British sculptors Henry Moore and Lynn Chadwick, alongside seminal post-war figures including Lucio Fontana and Yayoi Kusama.
A centrepiece of London’s 20/21 Century Sale in March, Modern Visionaries will debut through three dedicated auctions: an Evening Sale on 5 March, a Day Sale on 6 March, and an online sale running from 25 February to 10 March 2026.
Global previews will present this remarkable collection in Brussels, Hong Kong, New York and Paris. Join us for an unforgettable celebration of artistic vision.
