[Help] Emmanuel Villanis bust

I'm wondering if this sculpture I inherited 10 years ago from a woman in Maryland is an authentic E. Villanis or a lovely replica? Her name is Melodie. There is a stamp on the back which is difficult to make out (I'm afraid to clean it too hard); the stamp ends with 'de Paris' and the letters JP are near the stamp. There is also an E. Villanis signature on the side. Pics included.

TYIA for any and all help!
