Superb bold autograph on a nicely-illustrated broadside advertising the "First Joint Concert in the United States," at NY's Avery Fisher Hall. In the late 1960s through the mid-70s, Shankar and Menuhin collaborated on a series of unprecedented concerts, the highlights of which were later released as the album "West Meets East." Menuhin was largely responsible for bringing a Western audience to Indian classical music and the recordings he and Shankar made together remain popular today.
