From his collection of old postcards Oriol Vilanova has picked out a series of ten diptychs, scattered around the building. The photographs lying behind these reproductions were taken at the time of the International Exhibition of “Arts et Techniques dans la Vie moderne” [Arts and Techniques in Modern Life] held in Paris in 1937 (the Palais de Tokyo was built for the same event). They show the German Pavilion and the Soviet Pavilion that challenged one another in a premonitory confrontation. Now symbols of power, now archives essential for the duty of remembrance, these postcards reveal the tenuous link between the commercial item and commemoration. A third way is also presented, that of Spain, with an “anti-war and avant-garde” Pavilion. Oriol Vilanova, born in 1980 in Barcelona, lives and works in Paris.
