All that can presently (July 2022) be gleaned about Catherine Cooper
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 between 1904 and 1906.
Her portrait on the left is taken from Sunlight and Shadow
(1904) music by Louis Tocaben
, words by Marc Sylvan and published by The American Advance Music Co.
