All that can presently (May 2022) be gleaned about
Rosa Rosalie from sheet music covers and by Internet searching is that
she was presumably an American actress/singer who has been featured on 2 works published in 1927.
Her portrait on the left is taken from
C'est Vous (1927) music by
Abner Greenberg, words by Abner Silver and Harry Richman published by
Irving Berlin Inc., New York, USA.
