Part.B.7, WITH EXTENSIVE ADDITIONS AND MARKINGS BY MAHLER THROUGHOUT in bright red ink, bearing the composer's stamp 'Gustav Mahler, Wien', 2°, contemporary cloth backed boards. THIS IS MAHLER'S OWN COPY OF BEETHOVEN'S THIRD SYMPHONY AND THEREFORE OF THE GREATEST IMPORTANCE. Mahler's annotations comprise extensive revisions throughout the symphony.
