This is an oil painting done by Potenza. It is very similar to her painting "The Loving Dance" http://www.potenzaart.com/the-loving-dance/ but you can see that it is different from the attached photos. The painting is 45" x 55".
I bought this painting at an estate sale in San Francisco in 2007. I have no knowledge of how it was originally acquired.
