Balanchine, George - Robbins, Jerome - Signed Original JEWELS Poster

Very rare poster from the 1970s, from the then recently premiered production of Balanchine´s "Jewels". He created the choreography. This ballet became very popular and has been staged many times around the world after the original, first production with Balanchine and the NY City Ballet in 1967..  Poster belongs to an original set of 3, each representing a precious stone: Diamonds (white), Emeralds (green) and Rubies (red). This poster corresponds to Diamonds, the part of "Jewels" that had music by Tchaikovsky.  Signed by George Balanchine, Jerome Robbins, plus a third, unidentified signature over the center, near the right border. Signatures have faded a bit but are still very clearly visible. Poster is 13.25 x 25 inches, has minor stains and damage over borders, but still is in very good condition.
