From 14th January to 26th February is held the first institutional retrospective “Yves Klein: Monochrome und Feuer” at the Haus Lange Museum in Krefeld. The retrospective is organised in close cooperation between Yves and Paul Wember, the museum director. Yves Klein realizes there his most important retrospective. He exhibited blue, pink and gold monochromes, his Air Architecture project, the Void room, an immaterial space that has since been part of the permanent collection of the museum. The Wall of Fire on the outside, is made up of 50 burners aligned. The lighting of the elements, in the dark, is spectacular. The rosettes in the form of daisies show, if approached, the decomposed colours of the flame: blue, gold and pink. Not far from the Wall is the flame of the Fire Sculpture. On February 26th, the closing date of the exhibition, Klein made the first Fire Paintings. A large sheet of paper or cardboard is offered to the flames of the Bunsen beaks, and bears the mark of the rosettes alone, or rosettes accompanied by the trace of The Fire Sculpture.
