In My Lady's Boudoir (1903)

Kathryn Osterman was a legitimate actress who worked occasionally in the movies during the first decade and a half of the 20th century. This looks like a Mutoscope cut-down of an actuality released in 1900, "The Art of "Making Up"". In it, we see her from the rear, sitting in front of a dressing mirror, putting up her hair and powdering her face.

Unfortunately the movie In My Lady's Boudoir is not yet available on Disney Plus.
