All that can presently (August 2024) be gleaned about
Carlotta St. Elmo from sheet music covers and by Internet searching is that she was presumably an American actress/singer who has been featured on 4 works published between 1911 and 1914.
Her portrait on the left is taken from
The Roulette Reel (1911) music by
Thomas Henry Lodge, words by Marie Theresa Laing and published by
M. Witmark and Sons, New York, Chicago, San Francisco, USA.
Surfers are welcome to contribute any further information about this performer.
