Diamonds are forever "Diva" chair

Hello!!
I was wondering if any of you could please help me. I have a Betty Boop figurine that I'm looking to sell on ebay soon but can't find any info on it!

The only thing i could find was something on a site called worthpoint.com, it just gave me info that i already knew because it's stamped on the bottom! (height, LE, hand painted, musical, maker etc...)

This isn't my photo (i took it from the worthpoint website!)



I just wanted to know if anybody knew if this was hard to get hold of, or rare? What it might be worth? Anything like that because I'm clueless! She's really lovely but i must part with her!

I've had her a long time so any info is much appreciated, thank you!!!
