This tryptic was executed in 1961 for the exhibition "Monochrome und Feuer" at the Haus Lange Museum, Krefeld. It contains a blue and a pink silkscreen, as well as a cardboard box coated in gold foil with gold leaf by Yves Klein. The three sheets were rendered in the signature colours of the artist: International Klein Blue, rose and gold (to which Klein added three appliques of gold leaf) and have become iconic examples of the artist's work.
“ I did not like the nothing, and it is thus that I met the empty, the deep empty, the depth of the blue. „
