All that can presently (October 2023) be gleaned about
Ethel Rosevere from sheet music covers and by Internet searching is that she was presumably a British actress/singer who has been featured on just 2 works published between 1923 and 1928.
Her portrait on the left is taken from
Pyjama Blues (1923) music by
Melville Morris, words by
William K. Wells and published by
Lawrence Wright Music Co., , London W.C., England.
Surfers are welcome to contribute any further information about this performer.
