The names on the back of the "fan drill" are from left to right (as best as I can translate my grandmother's handwriting) Mary Autmou, Eula Crain, Mattie Toler, Edna Mullins, Nora Thomas (Thomas is her step-father's last name, her last name was Demasterson; this is my grandmother), Eva Murphy, Ora Thomas (Nora's half-sister), Lola Toler, Edna Nickleson, Flora Thomas (really Demasterson; this is Nora's twin sister), Mary Mullins, Kizzie Rainer.
(I have scaned the back with her handwriting also.)
