Extraordinary signature and musical quotation in his own hand on autograph book page (4.5x6"). From the great American composer who boldly defined a new musical idiom this is of his most important composition. Done in a rich black fountain pen, the signature, thick and bold looks great. Signature rates a perfect 10 out of a possible 10. Dated 1932 and he has added a bar of music below. Matted together with photo. Framed to 11x21". Gershwin signed musical quotations are extremely rare, let alone of one of the most important pieces of American music ever written.
