There are no known public exhibitions with this title listed. In the late teens and early twenties, Sharp was producing a good number of firelight scenes, usually identified by sitter.  One that appeared at the Hotel Gibson galleries in 1922, titled Firelight Song, is generic enough to suggest this work.

There is a related small sketch titled Crucita, Taos Indian Girl that may be a study for this work.  See related image, #620.
