What can you tell me about my table?

This beautifully carved table belonged to an iconic celebrity who grew tired of the piece and had moved it to the security guard kiosk on the property of her Los Angeles home before giving it to her sister.  Her sister didn't have the right spot for it and gifted it to me.  I have had it for about six years now and love it.  While watching Antiques Roadshow recently it occured to me that it may have some value beyond its providence.

Good
