The Haus am Waldsee in Berlin, together with the Staatliche Graphische Sammlung in Munich, showed the exhibition "Missing! The Tower of Blue Horses by Franz Marc" from March 3 to June 5, 2017. For this exhibition, the exhibition organizers invited artists to deal with Franz Marc's most famous work and his fate. Norbert Bisky's installation shows a torn picture with burn marks. The artist had repainted Marc's painting in its dimensions of 200 by 130 centimeters and recreated the frame and the back with the inventory numbers of the National Gallery and the Nazi "Degenerate Art" campaign almost faithfully to the original. He then demolished the work. With the violent installation, he not only reflects a possible version of the fate of this picture, but also vividly visualizes Marc's death in the war, the violence against art and the ostracism of artists in the "Third Reich". The painting “Tower of Blue Horses” was exhibited immediately after its creation in 1913 at the autumn salon of the Berlin gallery “Sturm”. After its brief presentation at the “Degenerate Art” exhibition in Munich in 1937, it was lost in the post-war period. The last known owner was Hermann Göring, who had taken the painting for his art collection after it was removed from the “Degenerate Art” exhibition in 1937. Perhaps the painting was destroyed in the Second World War. On the other hand, there were witnesses from the spring/summer of 1945 and the winter of 1948/1949 who claimed to have seen the painting, which supposedly still exists. How one should imagine the picture, of which no color image exists, is shown by a colored postcard that Franz Marc created as a greeting for the turn of the year 1912/13 to his artist friend Else Lasker Schüler. It is now in the State Graphic Collection in Munich. There is still speculation about the whereabouts of Franz Marc's painting "The Tower of Blue Horses". This painting is considered a masterpiece of German Expressionism and a central work of the "Blue Rider" artist group.
