Vasarely, Victor. UNTITLED COMPOSITION. Serigraph in black, grey-green and grey on white paper. Signed in pencil and with the blindstamp of Editions Denise Rene (Vasarely was a founder of the Denise Rene Gallery, of which Editions Denise Rene was the publishing division. Most of Vasarely's prints were published by and marketed through Galerie Denise Rene. This striking design, in which a four-color effect is produced using only two inks (one color from each, one from overlaying the two colors, and one from the white paper, varies from the geometric and "op-art" designs with which Vasarely is usually associated. The print has no date, title or edition size designated, but is likely one of 100, 150 or 200, which were the usual sizes of his editions. Image 16 x 13 1/2 inches, 406 x 343 mm.; sheet 26 x 20 inches660 x 508 mm. Two soft creases visible in left margin, else in excellent condition. Hamdsomely framed.
