The woman in the picture is as close to the real Maleficent as you can get- it's Eleanor Audley, the woman who provided the voice for both Maleficent in Sleeping Beauty and the evil Stepmother in Cinderella.
She enjoyed dressing up in costume when not in the recording studio, and often acted out the roles so Disney animators could study her facial expressions and movements.
