Although Aida Overton Walker (1880-1914) is little-known today, she was a premiere vaudevillian performer in her own day. Some historians even credit her with popularizing the cakewalk. When she could no longer perform for health reasons, she became an integral force for raising funding for the Industrial Home for Colored Working Girls.
Here she is at her sultry best. The photo is undated but my guess is that it was taken in the early 1900s, at the height of her career.
