Mix media on board framed. Featuring textured surface mixed media artwork. Signed and attr. Yves Klein (French, 1928-62). Signature on lower right corner. 15.4 x 7.9 inch (39 x 20 cm). Yves Klein is best known for his trademark ultramarine pigment, which he patented as International Klein Blue in 1961. "Blue…is beyond dimensions, whereas the other colors are not," he said. "All colors arouse specific ideas, while blue suggests at most the sea and the sky; and they, after all, are in actual, visible nature what is most abstract." Starting in the mid-1950s, Klein made retinal blue monochromes (which would prove cornerstones of Minimalism) and the pigment would also feature prominently in his Anthropometry paintings.
