Here’s the third of three photos from the January 3 1933 edition of the Toronto Daily Star featuring a woman with unusually thin eyebrows by modern standards. The previous two women had thin horizontal eyebrows, whereas those of singer Alice Joy were more curved but equally unusual:

Alice Joy, whose given name was Frances Holcombe, appeared on radio throughout the 1930s. Her show was titled Alice Joy, the Dream Singer, and Time magazine once stated that her voice had “a saxophone quality so deep that it might be a man’s”. I couldn’t find out anything about what happened to her after she stopped singing on the radio.
This link indicates that her show was sponsored by Prince Albert tobacco. (“Have you got Prince Albert in a can?”)
