Obscure Artist Anna Robinson

Ive spent the better part of 5 years trying to find a picture of this woman. So far too no avail. She was just part of the 1930s jazz Harlem scene. How I found out  about her was researching Pianist Teddy Wilson who loved her singing way more than Billie Holiday who he had a successful musical relationship in the 1930s so I'd always check out biographies to try to find a picture of her but to no avail. I'd probably be disappointed she seems to have been just another character in a scene from long ago. But I finally found this small clipping so that's progress. http://www.allmusic.com/artist/anna-robinson-mn0000575783
