Wember lists a total of 194 blue monochrome paintings of widely varying sizes. They were numbered after the artist's death by his widow Rotraut Klein-Moquay, not in chronological order, 'IKB 1-194', the letters IKB standing for International Klein Blue, a reference to the very distinctive ultramarine blue which Klein employed. Klein made his first monochrome painting in 1949 and began his so-called 'blue period' in 1957; he then continued to make blue monochrome paintings on and off right up to his death in June 1962. It is difficult to date most of them precisely, though the early pictures tend to have a distinctly uneven wave-like surface, whereas the later works (such as this one) are finer and more uniform in texture.
Mme Klein-Moquay said on 6 May 1974, after re-examining the Tate's picture, that she was fairly certain it was one of about four in the same style which Klein made at Gelsenkirchen in 1959. She was with him at the time.
