No known credit for the photographer I’m afraid.
This is the outstanding, inspirational Sister Rosetta Tharpe on the far left of the photo. The first superstar gospel singer in 1930s and 1940s America who played a mean electric guitar.
In the photo with Rosetta, admiring her talent, are Hot Lips Page, Duke Ellington, Cab Calloway and J.C. Higginbotham.

Not dainty work but there is something elegant about her posture.
