Bump!
This is an outstandingly celebratory picture.
The folk here are not necessary "liberated" and generally extrovert, although they could be. Sometimes such a dancer can be a very quiet woman with a job like a nurse or store clerk. Dancing however, unites folk in a wonderful way.
This woman has extraordinary confidence and a sense of joy and worth.
She is a person to salute!
.......and the picture too!
