The role of art at world exhibitions was exemplified in the context of Paris 1937, New York 1939/40, Brussels 1958, Montreal 1967 and Osaka 1970 in the dialog between art, design and architecture in a cooperative exhibition with the Marta Herford. The exhibition ranged from panel paintings to environments as an expression of the change in artistic forms of expression. Historical works by artists such as Robert Delaunay, Salvador Dalí, Lionel Feininger, Le Corbusier, Heinz Mack and Jean Tinguely are brought together in a lively presentation. As a cooperation between the Marta Herford and the Kunstmuseum Ahlen, the show was presented simultaneously with different focal points. In the Ahlen Art Museum, historical originals were in dialog with selected pictorial and film documents. At Marta Herford, the central themes of the world exhibition between man, science and technology were placed in current contexts through newly developed contributions by contemporary artists, including Mathieu Kleyebe Abonnenc, Tim Berresheim, Robert Breer, Angela Fette, Nikolaus Gansterer, Konsortium (Lars Breuer, Sebastian Freytag, Guido Münch), Katja Novitskova, Yvonne Roeb, Rob Voerman and others.
