The artist is Puni
AT „Still life with letters. Spectrum flight “The verbal basis of the figurative solution is obvious. In a word „flight “letters randomly scatter, in the word „Spectrum “ – arise on the surface of the canvas, just as the directed floodlight beam expands, and the word „forms “with a triple letter „m “gives rise to a sense of length. Later at his personal exhibition in the gallery „The assault “In Berlin (1921), Puni in the new version repeated this plastic move, installing the word „Flight "on the walls of the exhibition hall. He repeated then and the work itself, which he could not get from Russia.
