BELA BARTOK(1881 - 1945) Hungarian composer and pianist. Bold signature in ink "Bela Bartok" beneath that of his wife DITTA PASTORY BARTOK, both penned on an 8 1/" x 11" sheet of unlined page from a guest book. Eleven other notables have also signed, including the scarce Russian pianist SIMON BARER, and American author ELMER DAVIS. On verso eight others have signed, including French author ANDRE MAUROIS. Just a touch of age-toning, overall very good to near fine condition.
