Vintage Black Cameo Bakelite Brooch. Victorian lady on the front. Unique

I’ve been wearing this on my little JCrew jacket for over 10 years. Unique and fun! She’s a beauty. 2” high and 2.5” long. Looks like one of the prongs on the right side, at about 4 o’clock, is missing. The cameo is still very secure in place. Who’s next?
