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 achieved 146% of the low estimate, underscoring Christie’s unmatched expertise in bringing collections to market.
About Roger and Josette Vanthournout

Roger and Josette Vanthournout were a Belgian couple whose shared passion for art shaped more than sixty years of collecting. Roger, trained in design and decoration and later the founder of a successful furniture manufacturing business, approached art with an architectural eye; Josette, a painter with a refined sense of colour and composition, brought an artist’s sensitivity to every acquisition.
Together, they embodied Belgium’s long-standing tradition of looking outward – a spirit rooted in the country’s history as a cultural and commercial crossroads. In the tradition of Belgian collectors who looked beyond their borders, they embraced diverse artistic currents, with an outward-looking spirit which recalls the prominence of Flanders in the 15th and 16th centuries, when the region stood alongside Venice, Genoa and Amsterdam as a major hub of European trade with the East. That same entrepreneurial openness animated the Vanthournouts’ own journey.
From the mid-1950s onwards, they travelled widely, engaging directly with artists, dealers and galleries, and embracing diverse artistic currents with a quietly confident eye. Their taste evolved continually: early interests in Chinese ceramics and Flemish Expressionism gave way to Surrealism, Minimalism, and leading strands of Post-War European and American art, and their home in Flanders became a carefully choreographed environment where sculpture played a central role, surrounded by paintings, works on paper and photography selected for the dialogues they created.
