All that can presently (June 2024) be gleaned about Eleanor Waldom from sheet music covers and by Internet searching is that she was presumably an American actress/singer who has been featured on just one work namely Minnie-Ha-Ha Donohue (1908) music by Theodore F. Morse, words by Jack Mahoney and published by F. B. Haviland Publishing Co. Inc., New York, USA
Her portrait on the left is taken from that same work.
